2. Preventing pregnancy and STI (Peipert 2008): computer‐delivered; tailored versus non‐tailored intervention.
| Outcome at 2 years1 | Intervention % | Comparison % | Adjusted relative risk (95% CI) | |
| Dual‐method use2 | initiated | 82 | 68 | 1.52 (0.96 to 2.41) |
| sustained3 | 19 | 24 | 0.89 (0.45 to 1.75) | |
1Results as reported by researchers in Peipert 2011; insufficient data for analysis in this review. 2Reportedly used a multinomial logistic regression model for a three‐category outcome: no dual‐method initiation (as reference), initiated and sustained dual‐method use; adjusted for education, substance use, baseline contraceptive use, and stages of change. 3Reported at 2 or more follow‐up interviews.
