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

The intrauterine device (IUD), primarily in the form of the copper IUD, is used by more than 150 million women around the world, making it the most widely used reversible method of contraception. With a remarkably low failure rate of less than 1 per 100 women in the first year of use, the Copper T-380A is in the top tier of contraceptives in terms of efficacy. Risks of utilization include perforation and an increased risk of infection in the first 20 days following insertion. Overall, the number of adverse events is low, making the Copper T-380A a very safe contraceptive method. The most common reasons for the discontinuation of this method are menstrual bleeding and dysmenorrhea. However, cumulative discontinuation rates of Copper T-380A are lower than that have been reported for other methods, indicating that the Copper T-380A is highly acceptable to women. After 5 years, approximately 50% of all women, who have a Copper T-380A inserted, will continue to use this highly effective contraceptive method.
