IQR Interquartile Range, CCT Conditional Cash Transfer, PHQ-9 Patient Health Questionnaire
^aAnalysis limited to individuals who did not receive the conditional cash transfer intervention (n = 217) in order to avoid possible mixing of effects
^bFor continuous variables, p-values were calculated using the Wilcoxon Rank Sum test. For categorical variables, p-values were calculated using Pearson’s χ² test. All tests used complete case analysis (i.e., omitting missing observations)
