The sentences
Several conceptually important covariates—BMI/obesity prevalence, average annual working hours, GDP per capita, and, in Models 2–3, urban population share—did not reach statistical significance and warrant cautious interpretation.
Statistical significance was interpreted at a 5% type I margin of error and extended to 10% for marginal significance interpretation.
The intercept term ( p < 0.001) and the sensitivity parameter (φ = 84.2, p < 0.001) of the model were highly significant and the Pseudo R2 value of the model was 0.398, indicating that the model explained approximately 40% of the variance in the dependent variable (Table 3 ).
