1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundEnsuring effective and long-term contraception in the immediate postpartum period is an effective strategy for reducing unplanned pregnancies. In the meantime, the intrauterine device (IUD) is an excellent option. The aim of our study was to evaluate the best way to insert post-placental IUDs in the immediate postpartum period. Discomfort during insertion, expulsion rate, uterine perforation rate, and proper positioning 40-60 days postpartum will be analyzed.

methodsRandomized, controlled, open clinical trial. The study group will be composed of women between 18 and 43 years old who are admitted for vaginal birth at the Women's Hospital of the State University of Campinas and who wish to use the IUD as a contraceptive method. The sample will be randomized into two insertion groups: manual and forceps. To calculate the sample size, the method of comparing the proportion between 2 groups was used, setting the level of significance alpha at 5% (alpha=0.05) and the power of the sample at 80% (beta=0.20). Based on the results, it was estimated that a sample of n=186 women (n=93 with manual insertion and n=93 with forceps) would be representative for comparison of expulsion between the 2 groups. All participants will undergo a postpartum consultation 40-60 days after birth with transvaginal ultrasound to assess the proper placement of the IUD. DISCUSSION: Insertion of an IUD in the immediate postpartum period has been considered a good option to increase coverage and access to contraception, and its benefit outweighs the inconvenience of a higher expulsion rate.

trial registrationThis study was approved by the Ethics and Research Commission of UNICAMP (CAAE: 50497321.4.0000.5404) and the Brazilian Registry of Clinical Trials (REBEC) (number RBR-4j62jv6). This is the first version of the study protocol approved on 11/12/2021 prior to the start of participant recruitment.
