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

Menstrual cups are increasingly used to control menstrual bleeding. Complication rates are sparsely described, but some serious complications have been reported. We present a rare case of ureterohydronephrosis due to a menstrual cup. A woman in her 30s presented with intermittent flank pain and occasional haematuria. CT urography showed a menstrual cup placed in the right side of the vagina in close proximity to the ureteral ostium together with ureterohydronephrosis. After removal of the menstrual cup, there was a complete regression of symptoms and ultrasonic regression of the ureterohydronephrosis. More awareness should be made, both among menstrual cup users and clinicians, about presenting symptoms and how to choose the correct shape, size, and insertion method to avoid complications.
