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

introductionTraction alopecia (TA) is a form of hair loss from excessive tension due to specific hairstyling practices. It disproportionately affects black women, including children.

objectiveOur study aimed to review the trichoscopy of TA.

methodsA literature search was performed in the scientific database PubMed for articles published between 1958 and 2023, using the terms "traction alopecia," "black scalp," "trichoscopy," and "dermoscopy."

resultsThe most frequent findings were vellus hair, hair casts, black dots, broken hairs, and white dots. Reduction in hair density, hair diameter variability, empty follicle openings, and vellus hairs may appear early or later during the disease course.

conclusionsTrichoscopy is a crucial diagnostic tool if associated with a suggestive clinical history. Despite non-specific, its common clinical findings offer relevant information about the disease's progress.
