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

Clinical observations indicate that some male patients with androgenic alopecia show varying degrees of hairline recession in the frontal and temporal regions on both sides, often with noticeable asymmetry between the left and right, which suggests a potential link to certain lifestyle habits. In this study, 161 male patients with androgenic alopecia were included, all exhibiting an "M"-shaped hairline. Patients' sleeping positions and combing directions were recorded and the areas of hairline recession in the frontal and temporal regions were calculated. Analysis of variance showed a significant difference in the ratio of the left and right receding hairline areas among patients with different sleeping positions (left lateral 1.19 ± 0.15 vs. right lateral 0.90 ± 0.10 vs. supine 1.00 ± 0.15 vs. no fixed position 1.00 ± 0.14,
