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 registryThe 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.

6 · The paper itselfAbstract
We quantified incident pregnancies among reproductive-aged women with and without Schistosoma haematobium infection. Among 245 women, 59 (24.1%) became pregnant during a median follow-up of 370 days. Women with S. haematobium infection had a 52% lower rate of pregnancy within the study period compared with uninfected women (hazard ratio = 0.48 [0.29-0.80], P = .005).
