Table 4 Logistic regression results for the effect of SMS reminders on malaria and non-malaria drug-taking

From: SMS messages increase adherence to rapid diagnostic test results among malaria patients: results from a pilot study in Nigeria

Medications taken Percentage (N) SMS SMS
  SMS sent (n = 117) SMS not sent (n = 123) SMS risk ratio (95% CI) Risk difference (95% CI)
1 Took anti-malarial 23.1% (27) 41.5% (51) 0.42 (0.25–0.72) −18.4% (−30.1% to −6.7%)
2 Took anti-malarial**    0.37 (0.20–0.69) −20.6% (−32.5% to −8.8%)
3 Took symptom drug 73.5% (86) 80.5% (99) 0.67 (0.37–1.20) −7.0% (−17.3% to 3.31%)
4 Took symptom drug**    0.89 (0.42–1.90) −2.1% (−15.2% to 11.1%)
  1. Sample includes RDT negative participants who bought both an antimalarial drug as well as drugs to treat their symptoms, N = 240.
  2. **Controls for city survey was conducted (Ibadan/Ogbomosho), treatment* city survey was conducted, whether assignment to the treatment/control group was made off-protocol, and treatment* whether survey assignment to the treatment/control group was made off-protocol (Model 3).
  3. Standard errors are clustered by retail site.
