Descriptive statistics for WHO-5 scores (mental well-being), self-rated health and diseases. For A and B, a bootstrap hypothesis test of equality between the both groups was applied with gender being equal (p value = 0.55) and wealth group being significantly different from each other (p value = 0.04), indicated by a reference band in grey. For B, least poor implies to the upper wealth index quintile, while most poor implies to the lowest. Note that for C and D, a WHO-5 scored 13 or above has been found to be indicative of good mental well-being in high-income country settings (cf. horizontal line).
