Coefficients for additional covariates are available in Table S7.

a

Sex on substances was only measured at wave two and wave three.

b

We did not adjust for education enrolment and days with three meals as we expected them to lie on the causal pathway between receipt of social grants and study outcomes.

c

Wald p-value for equality across pairs of within-person and between-person coefficients.

A significant p-value indicates that pairs of coefficients are different from one another.

d

Wald p-value for significance.

A significant p-value indicates that a coefficient is significantly different from 1.00. Abbreviations: aOR, adjusted odds ratio; CI, confidence interval; AUC, Area Under Curve.
