Effects of the ECHO tele-mentoring program on HIV/TB service delivery in health facilities in Zambia: a mixed-methods, retrospective program evaluation

Table 5 DiD coefficients, relative changes, and absolute changes

Outcome	n	DiD coefficient (95% CI)^a	p value	Absolute change^b
HTS yield	1536	− 12.63 (− 32.50–13.09)	0.306	− 0.74%
OPD yield	1462	− 0.024 (− 25.47–27.63)	0.856	− 0.13%
Index yield	338	33.37 (− 20.15–122.78)	0.269	+ 5.37%
TPT completions	362	16.53 (− 11.84–54.03)	0.281	+ 16.53%
VL coverage	806	13.24 (4.11–22.38)	0.0046	+ 13.24%
VL suppression	934	− 0.98 (− 5.35–3.40)	0.661	− 0.98%

^aModel includes log-transformed outcome variable and DiD coefficient (95% CI) is exponentiated
^bAbsolute change is calculated by multiplying the DiD coefficient by the pre-intervention mean at ECHO sites (for models with log-transformed outcome variables) or is equivalent to the DiD coefficient (for models that do not have log-transformed outcome variables)
