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

contextHair restoration surgery for androgenetic alopecia (AGA) essentially involves various forms of hair transplantation. There is paucity of studies assessing donor area in Indian men and also no simplified guidelines are available for the safe donor area for follicular unit extraction (FUE). Our study is an attempt to study the donor area in Indian men.

aimsTo assess the density of follicular units (FUs) in the donor area, that is, both scalp and beard in Indian men, and to propose simplified guidelines for FUE. MATERIALS AND

methodsThe study design was cross-sectional and was carried out for 2 years. All the consenting male patients with male pattern hair loss Hamilton Norwood grading III or more who consulted for a hair restoration surgery were recruited. FU density was assessed in the donor area of scalp by drawing a rectangle with its lower border being a straight line joining two points, which are 27-28mm from the line drawn perpendicular to tragus, passing through external occipital protuberance. Three squares of area 1cm

resultsA total of 580 male patients were recruited in the study. Mean FU density in the scalp and beard was 78.2/cm
