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

objectiveTo evaluate pregnancy risk following copper (CuT380A) intrauterine device (IUD) placement 6-14 days after unprotected intercourse. STUDY

designWe used a combined dataset from four protocols in which participants had received a CuT380A IUD regardless of recent unprotected intercourse. At entry, participants had negative point of care urine pregnancy testing and reported all acts of unprotected intercourse in the two weeks prior to IUD placement. We identified a subset of women who had placement 6-14 days after unprotected intercourse and provided follow-up information on pregnancy status 2-4 weeks after IUD insertion. This follow-up within the four protocols included self -administered home urine pregnancy test (UPT) results 2-4 weeks after IUD placement or continued contact for up to 6 months.

resultsWe identified 134 women who had a CuT380A IUD placed 6-14 days after unprotected intercourse and provided follow-up information on pregnancy status. Ninety-five (71%) participants reported UPT results 2-4 weeks after placement and the other 39 women were followed for 6 months after IUD placement to assess pregnancy status. Zero (97.5% CI 0-2.7%) participants reported a pregnancy within four weeks of CuT380A IUD placement.

conclusionIn these collected data, no women with recent unprotected intercourse became pregnant within 1 month of CuT380A IUD placement. IMPLICATION: These data indicate a low likelihood of pregnancy among women who reported unprotected intercourse 6-14 days preceding IUD insertion. For many women and their providers, these data may be sufficient to support same-day placement of a copper IUD rather than delaying IUD placement until the next menses.
