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

backgroundDermoscopy of the scalp (trichoscopy) is a technique to evaluate the skin of the scalp and the hair disorders. It clinically helps to establish early female pattern hair loss (FPHL) without the need for more invasive techniques.

objectivesThis work intends to demonstrate new adjunct criteria for the clinical diagnosis of FPHL by determining the number of short vellus hairs encountered in the frontal area of the scalp of female patients with FPHL. MATERIALS AND

methodsWe retrospectively reviewed the trichoscopy images from 45 women affected by FPHL in initial stages, at 20 fold magnification dermoscopy at 2 cm from the hairline into the frontal area of the scalp.

resultsA total of 45 patients images included had more than 20% variability at dermoscopy, criteria utilized to diagnose and included them in the study. All patients were graded as Ludwig I severity, 14 patients had frontal accentuation. The average number of vellus hairs in the frontal area at 20-fold magnification of all patients was of 12.02 vellus hair in the frontal area. When comparing the Ludwid I pattern group versus the Ludwig I with frontal accentuation pattern group there was no statistical difference between the two clinical groups.

conclusionsAll 45 patients analyzed in this study were clinically diagnosed with FPHL. The number of vellus hairs in the frontal area was greater than the average found in normal subjects. Most patients (80%) with FPHL had more than or equal to seven vellus hairs per 20-fold magnification field in the frontal area, therefore we suggest that the presence of more than 6 vellus hairs in the frontal scalp at 20-fold magnification can be used as an additional criterion of FPHL.
