| Sample Proportions, N (%) | Risk Ratio*, (95% CI) | Risk Difference†, (95% CI) | ||||
| Timepoint for Follow-Up | Comparison (n = 32) | Intervention (n = 39) | Unadjusted‡ (n = 71) | Adjusted‡ (n = 71) | Unadjusted‡ (n = 71) | Adjusted‡ (n = 71) |
| 30 days | 5 (15.6) | 16 (41.0) | 2.66 (0.90 to 7.87) | 3.01 (1.45 to 6.25) | 27.0 (-10.0 to 63.9) | 28.6 (-8.1 to 65.2) |
| 60 days | 6 (18.8) | 20 (51.3) | 3.05 (1.75 to 5.31) | 3.31 (1.60 to 6.84) | 37.2 (10.5 to 63.8) | 38.5 (13.2 to 63.9) |

*Computed using generalized estimating equations with Poisson distribution and log link (exponentiated parameters); 95% confidence intervals incorporate Kauermann-Carroll (KC) correction to SEs.
†Computed using generalized estimating equations with Gaussian distribution and identity link; 95% confidence intervals incorporate Kauermann Carroll correction to SEs.
‡Unadjusted regressions include treatment and strata indicators only; adjusted include female sex, age (range 3–5 years), and highest educational attainment by any parent/guardian (≤high school diploma/GED or at least some college).
§Secondary outcome of interest, p = 0.028 computed using stratified permutation test.
