Table 7.

Effect of SMS on TB adherence using the difference in difference analysis.

	Adherence to TB Treatment, N (%)
	Baseline, n (%)	End Line, n (%)	Difference,^a n (%)	DID^b (%)	p
Intervention [N = 105]	60 (57.1)	72 (80.9)	12 (23.8)	30.7	<.001
Control [N = 125]	73 (58.4)	52 (51.5)	−21 (−6.9)	30.7	<.001

Note. SMS: short message services; TB: tuberculosis DID: difference-in-differences.

^{^a}

Difference (absolute) in pre- and postintervention proportions of participants who were part of either the treated or control group obtained from a two-sample test for binomial proportions (normal theory test).

^{^b}

Two-tailed p value for the DID. Sample sizes are in squared brackets.
