Treatment Adherence among HIV and TB Patients Using Single and Double Way Mobile Phone Text Messages: A Randomized Controlled Trial

Table 7

Adherence to ART between the single-way and double-way SMS and control of the groups before and after 6 months of intervention.

Assessment	Group	Level of adherence		Effect estimate
		Poor No (%)	Good No (%)	RR (95% CI)	-value
Baseline	Control	49 (70.0)	21 (30.0)	1.00 (0.81-1.24)	1.000
	Single-way SMS	49 (70.0)	21 (30.0)
	Control	49 (70.0)	21 (30.0)	1.04 (0.83-1.31)	0.716
	Double-way SMS	47 (67.1)	23 (32.9)
After 6 Months intervention	Control	29 (54.7)	24 (45.3)	0.99 (0.71–1.39)	0.962
	Single-way SMS	32 (55.2)	26 (44.8)
	Control	29 (54.7)	24 (45.3)	1.06 (0.75–1.50)	0.746
	Double-way SMS	31 (51.7)	29 (48.3)

RR = risk ratio; CI = confidence interval; SMS: short message service.
