	Hospital-affiliated: all visits	0.01 (−0.5, 0.5)	0.96
3	Outreach: Difference between visit 6 month after transfer and last visit before transfer
	Hospital-affiliated: Difference between visits at 6 months intervals	0.4 (−0.07, 0.8)	0.10

CI: Confidence interval; WAZ: weight-for-age z-score.

Estimates and p-values for comparisons from linear regression with GEE to account for repeated measures per child.

Adjusted for month on ART, age at ART initiation, underweight at ART initiation and severe immunosuppression at ART initiation.
