Levonorgestrel-releasing intrauterine device therapy vs oral progestin treatment for reproductive-aged patients with endometrial intraepithelial neoplasia: a systematic review and meta-analysis.
Synthesis in Journal of the National Cancer Institute, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundWe conducted a systematic review and meta-analysis to examine outcomes of patients with endometrial intraepithelial neoplasia treated with oral progestins or a levonorgestrel-releasing intrauterine device (IUD).
methodsWe conducted a systematic review across 5 databases to examine outcomes of progestational treatment (oral progestins or levonorgestrel-releasing IUD) for patients with endometrial intraepithelial neoplasia. The primary outcome was the best complete response rate within 12 months of primary progestational treatment. Sensitivity analyses were performed by removing studies with extreme effect sizes. Secondary outcomes included the pooled pregnancy rate.
resultsWe identified 21 eligible studies, including 824 premenopausal patients with endometrial intraepithelial neoplasia, for our meta-analysis. Among these, 459 patients received oral progestin, and 365 patients received levonorgestrel-releasing IUD as a primary progestational treatment. The pooled best complete response proportion within 12 months was 82% (95% confidence interval [CI] = 69% to 91%) following oral progestin treatment and 95% (95% CI = 81% to 99%) following levonorgestrel-releasing IUD treatment. After removing outlier studies, the pooled proportion was 86% (95% CI = 75% to 92%) for the oral progestin group and 96% (95% CI = 91% to 99%) for the levonorgestrel-releasing IUD group, with reduced heterogeneity. The pooled pregnancy rate was 50% (95% CI = 35% to 65%) after oral progestin and 35% (95% CI = 23% to 49%) after levonorgestrel-releasing IUD treatment.
conclusionsThis meta-analysis provides data on the effectiveness of oral progestins and levonorgestrel-releasing IUD treatment within 12 months of treatment among premenopausal patients with endometrial intraepithelial neoplasia. Although based on small numbers, the rate of pregnancy after treatment is modest. These data may be beneficial for selecting progestational therapies that allow fertility preservation for patients with endometrial intraepithelial neoplasia.
