To align with the 2030 vision of the World Health Organization (WHO) to ensure 90% of girls receive the HPV vaccine before turning 15, Bangladesh has recently started the (HPV) vaccine campaign nationwide. Therefore, our study aimed to assess the level of its acceptance among parents of eligible daughters in Bangladesh.
Methods
This nat...
Background
Vaccination against Human papillomavirus (HPV) is recommended to avoid HPV infections and its associated diseases, including cervical cancer. However, there is no awareness study among Bangladeshi population.

Introduction On the verge of vaccination, the most pressing issue seems to be vaccine hesitancy. In this era of communication, Bangladeshi people may have pre-determined concerns about receiving the vaccines. Accordingly, our study attempted to understand belief, attitude, and intention to take the COVID-19 vaccine among the country’s adult populat...
Background:
The COVID-19 pandemic posed a danger to global public health because of the unprecedented physical, mental, social, and environmental impact affecting quality of life (QoL). The study aimed to find the changes in QoL among COVID-19 recovered individuals and explore the determinants of change more than 1 year after recovery in low-resou...

Considering the adverse outcomes of thunderstorm‐mediated lightning in recent years, this study aimed to identify the most thunderstorm‐and‐casualty prone regions and seasons in Bangladesh, via geospatial mapping. We attempted to forecast the number of yearly thunderstorm (TS) days for each meteorological station and district‐level lightning casual...
Background
The global outbreak of COVID-19 has created unprecedented havoc among health care workers, resulting in significant psychological strains like insomnia. This study aimed to analyze insomnia prevalence and job stressors among Bangladeshi health care workers in COVID-19 units.

We conducted this cross-sectional study to assess...
Objective:
To investigate the prevalence of the number of children ever born (CEB) and its associated determinants among women aged 15-49 years in Bangladesh.
Study design and setting:
We used clustered data extracted from the last two Bangladesh Demographic and Health Surveys (BDHS 2014 and BDHS 2017-2018). A two-stage stratified sampling was u...
Background
Health care workers have been facing difficulties in coping with the COVID-19 infection from the beginning. The study aimed to compare Quality of Life (QOL) among health care workers (HCWs) with and without prior COVID-19 disease.
Methods
This study was conducted from July 2020 to January 2021 among 444 HCWs. We randomly interviewed 324...
Oral health is a critical component of human health but is sometimes forgotten, particularly during humanitarian crises. This research aimed to ascertain the state of oral health among Rohingya refugees living in one of the largest refugee camps and evaluate their knowledge and practice of oral health. A multicenter cross-sectional survey was condu...
Background: Evaluating potential vaccine side effects is often a prerequisite to combat the coronavirus disease 2019 (COVID-19) pandemic more effectively in a low-resource setting where herd immunity could be the most feasible option.
Case report: Here, we present, an 80-year-old man with multiple comorbidities was admitted into the coronary care u...
A time-series modeling tool SARIMA (4,0,4)(1,1,1) [12] model has been implemented to project the total number of monthly thunderstorm-days at 34 different meteorological stations in Bangladesh. Efforts have been made to determine, as accurate as possible, the future number of thunderstorm-days up to five years. Detailed modeling procedures and fore...
Objectives: With COVID-19 vaccination underway, this study aimed to understand belief, attitude and intention of the people in the South Asia region towards the vaccine. Methods: We conducted a cross-sectional study using semi-structured questionnaires among 18201 individuals in four South Asian countries; Bangladesh, India, Pakistan, and Nepal bet...
Polycystic ovary syndrome (PCOS) is a hormonal disorder which affects women in their reproductive ages. There might have association between maternal and neonatal complications with PCOS. The goal of this study is to look for the association between polycystic ovary syndromes (PCOS) and obstetric complications through meta-analysis on the basis of...
Coronavirus Disease-2019 (COVID-19) quickly surged the whole world and affected people’s physical, mental, and social health thereby upsetting their quality of life. Therefore, we aimed to investigate the quality of life (QoL) of COVID-19 positive patients after recovery in Bangladesh. This was a study of adult (aged ≥18 years) COVID-19 individuals...
A 77-year-old man with a past medical history of type 2 diabetes mellitus, peripheral neuropathy, and chronic obstructive pulmonary disease was admitted to the intensive care unit of Bangladesh Medical College Hospital with acute encephalopathy and non-ST segment elevation myocardial infarction (NSTEMI). The patient was on antidiabetic medicine alo...

Statistical analysts can encounter difficulties in obtaining point and interval estimates for fixed effects when sample sizes are small and there are two or more error strata to consider. Standard methods can lead to certain variance components being estimated as zero which often seems contrary to engineering experience and judgement. Shell Global...
Background
Globally, tuberculosis (TB) remains one of the top 10 causes of deaths and the leading cause from a single infectious agent. Delayed TB diagnosis and/or treatment may result in the transmission of bacilli, increasing infectivity, the risk of severe disease states, morbidity and mortality. It is essential to identify the factors that prol...

Industrial experimental design is an important area under design of
experiments and factorial design hold a firm place in industrial experiments.
The generalization of factorial designs results in split-plot type
designs when complete randomization of runs is not possible. More

Questions
Question (1)
I got a data set and codes as follows to estimate a variance component. In the data set "y" is the response, "fuel" has fixed and "day" has random effects in the linear mixed model. I can estimate random effect due to "day" and there is no option to have a p-value corresponding to the estimate of random effect. How can I estimate the p-value? Is there any other package for that? Any answer would be appreciated much.
day<-c(1, 1, 2, 2, 3, 3)
fuel<-c(1,1,1,2,2,2)
y<-c(32.32048, 32.28583, 31.97912, 33.61024, 33.33915, 33.63342)
