Positive association between the physical health and time spent in nature. Physical health is scaled from 0 (worst physical health), to 100 (best physical health). Time spent in nature is scaled from 1 (no regular time spent in nature), to 6 (every day activity in nature). The graph was created using the visreg function, which visualises the response variable treated on the effects of other significant variables represented in the minimum adequate model (MAM 1, Table 1).
