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

aimMyotonic dystrophy (MD) has been associated with an increased risk of endometrial cancer (EC) in Western countries; however, data from Japan are limited. This study aimed to evaluate the incidence and clinical characteristics of EC and its precursor lesion, atypical endometrial hyperplasia (AEH), in Japanese patients with MD.

methodsWe retrospectively reviewed medical records of female patients with MD (MD group, n = 36) and those with other types of muscular dystrophy (control group, n = 84) treated at a single institution between 2008 and 2023.

resultsEC/AEH was identified in 5 of 36 patients in the MD group (13.9%), including 3 cases of EC and 2 of AEH, whereas 1 case of EC (1.2%) was observed among 84 control patients, indicating a significantly higher incidence in the MD group (p = 0.014). The median age at diagnosis of EC/AEH in the MD group was 45 years, which was significantly younger than that of non-MD EC/AEH cases treated during the same period (median 59 years). All surgically treated EC cases were early-stage endometrioid carcinoma and achieved favorable oncological outcomes, although perioperative respiratory complications were observed.

conclusionsJapanese MD patients have a significantly higher risk of developing EC/AEH at a younger age compared with non-MD patients. These findings highlight the importance of regular gynecological surveillance in women with MD.
