Analysis
Our main outcomes were assessed after 6 weeks in an intention to treat (ITT) analysis of all eligible randomized participants (n=112) and a per protocol (PP) analysis of all participants that were followed up, either in person, by interview or by record review, according to the intervention received. Secondary outcomes were assessed at either 6 weeks, 3 months or 6 months post-abortion, according to ITT or PP as appropriate.
Continuous outcomes were summarized using medians and inter-quartile range for non-normal distributions and compared group-wise using Wilcoxon rank-sum (Mann-Whitney) tests. Categorical outcomes were compared using Chi-squared or Fisher’s Exact test depending on the size of the subgroup. A sensitivity analysis was performed to control for uncertainty of data in cases where IUD use was assumed based on self-report. Analyses were conducted in STATA v. 15, 2019 (StataCorp. College Station, TX, USA) and significance levels are reported at p<0.05.
