Risk ratio for utilising ORS with zinc in the intervention (Kalomo and Katete) versus comparator districts (Monze and Petauke, respectively) at endline, 2013
| Characteristic | GLM results | |
| Risk ratio (95% CI)* | P value | |
| Kalomo (intervention) versus Monze (comparator) (n=348) | 27.0 (10.6 to 69.1) | 0.000 |
| Katete (intervention) versus Petauke (comparator) (n=356) | 75.2 (10.3 to 547.7) | 0.000 |
Figures in bold font denote statistically significant values.
*GLM with Poisson distribution to estimate relative risk; adjusted for within-site correlation using the robust variance estimate.
GLM, generalised linear model; ORS, oral rehydration salts.
