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

To analyze the effect, side effects, and satisfaction of the second-generation radiopaque subcutaneous implant, providing healthcare workers a basis for propaganda and guidance. Methods: A total of 214 cases of healthy women with birth control requirements from August 2016 to June 2018 received ray subcutaneous implants. Quantitative surveys were administered 10 days, 3 months, 12 months, and 24 months later. All cases were implanted successfully. The number of effective cases was 211, with 3 cases lost to follow-up. The pregnancy rate of 211 subjects during receiving implant was 0. Changes in bleeding patterns (130 cases, 61.61%) remained the most common side effect event. The rate of withdrawal was 96.21% in the first year and 66.35% in the second year. There were 48 cases (67.61%) who withdrew due to the change of bleeding pattern. All participants with bleeding patterns were divided into the withdrawal group and the non-withdrawal group, and there were significant differences in educational background, number of pregnancies, abortion, and income between the two groups. According to the satisfaction survey, 37 (17.54%) were very satisfied, 109 (51.66%) were satisfied. The contraceptive rate of radiopaque subcutaneous implantation was very high, and there were no serious side effects while receiving an implant. The change of bleeding pattern was the main reason for withdrawal, which was related to educational background, number of pregnancies, history of abortion, and economic conditions. Pre-implantation consultation and post-implantation management should be strengthened.
