	Separately, adjusted for covariates*		Mutually adjusted for each other†
	Adjusted risk ratio (95% CI)	P-value	Adjusted risk ratio (95% CI)	P-value
Childhood trauma, by type
Physical abuse	2.16 (1.19–3.89)	0.01	1.37 (0.71–2.67)	0.34
Sexual abuse	1.58 (0.90–2.79)	0.17	1.17 (0.62–2.22)	0.63

^*Each cell represents the output of a single multivariable Poisson regression model fitted to the data, specifying major depressive disorder as the dependent variable and the row header as the primary explanatory variable of interest, adjusting for age, orphanhood, type of school (boarding versus day), bullying, HIV stigma, social support

^†The column represents the output of a single multivariable Poisson regression model fitted to the data, specifying major depressive disorder as the dependent variable and the three types of childhood trauma as explanatory variables, mutually adjusted for each other and for the other covariates listed above.
