Primary analysis: Adjusted relative risks (95 % confidence intervals) for performing tasks correctly for the full sample across arms and time periods

	Sets of clinical tasks
Effects	Patient history	Physical examination	Laboratory tests	Diagnosis	Treatment	Patient/caregiver education
Sample Size	N = 573	N = 639	N = 621	N = 674	N = 683	N = 667
Arm A vs. Arm B at time 0	1.02 (0.93-1.11)	0.97 (0.80-1.18)	0.85 (0.72-1.01)	1.14 (0.98-1.33)	1.00 (0.92-1.09)	1.07 (0.95-1.19)
Time 1 vs. time 0 in Arm B (IMID)	1.12 (1.04-1.21)	1.40 (1.16-1.68)	0.95 (0.82-1.09)	1.05 (0.91-1.21)	1.01 (0.93-1.10)	1.03 (0.92-1.16)
Change Arm A vs. Arm B (IMID and OSS), RRR	1.18 (1.06-1.31)	1.27 (1.02-1.59)	1.21 (0.97-1.49)	0.92 (0.77-1.10)	1.07 (0.96-1.19)	1.07 (0.94-1.23)

Estimates were adjusted for: sequence of clinical assessment, cadre of trainee, complexity of patient determined by number of diagnoses and age of patient less than one year, whether the health facility received support from the Health Care Improvement project or not, whether the facility received the on-site intervention from Baylor International Pediatric AIDS Initiative or not, and the clinical faculty determined by cadre of faculty and whether s/he attended relevant assessment training session or not

RRR = Ratio of relative risks comparing change in practice at time 1 to practice at time 0 across arms
