Comparison of the effectiveness of the levonorgestrel-intrauterine device and oral progestogens on regression of endometrial hyperplasia without atypia.

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.
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
Endometrial hyperplasia is caused by an excess of estrogen unopposed by progesterone. Oral progestogens are traditionally used for endometrial hyperplasia without atypia. However oral progestogen is not always successful at causing regression of endometrial hyperplasia. In addition, cyclic progestogens are less effective in delivering progestogen to the endometrium. Therefore, the levonorgestrel-intrauterine device (LNG-IUD), as an alternative option of delivery progestogen has been introduced in clinical practice. The effectiveness of LNG-IUD in causing regression of endometrial hyperplasia in the short-term had moderate-quality evidence, but the long-term (13 months to two years) effectiveness had low-quality evidence. In this study with relatively large sample size, we compared the effectiveness in the regression of endometrial hyperplasia without atypia for short-term and long-term between the treatment with LNG-IUD and oral progestogens or no treatment. Data on histology or ultrasound from 466 cases who received either LNG-IUD or oral progestogens or were untreated were collected. The primary treatment with LNG-IUD showed a 93% regression rate of endometrial hyperplasia, which was significantly higher than oral progestogens showing a 66% regression rate. The odds ratio of regression of endometrial hyperplasia in cases with LNG-IUD treatment was 7.128 (95%CI: 2.94, 16.76, p < 0.0001), compared to the cases with oral progestogen treatment. The regression rate in untreated cases was 16%. In addition, cases without regression by oral progestogens who then received the alternative treatment option by LNG-IUD also showed a 93% regression rate. While continuously receiving oral progestogens showed a 55% regression rate of endometrial hyperplasia, which was significantly lower than LNG-IUD treatment as an alternative option. Our data reports a significant response on regression of endometrial hyperplasia after LNG-IUD treatment in comparison with oral progestogen treatment.
