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

backgroundLong hair follicular unit excision (FUE) is the most state-of-the-art surgical technique in the field of hair transplantation surgery. Long hair FUE reduces the signs of surgery by camouflaging the recipient area with long hair, and allows hair curl identification when placing grafts. In addition, donor area shaving can be omitted.

methodsThis article presents the surgical approach and methods of long hair FUE. Patients were categorized by sex, age, recipient site, purpose of the surgery, and history of previous hair transplantation. Medical charts and photographs were reviewed to obtain the transection rate and calculated density for each patient.

resultsLong hair FUE was applied to 134 patients (112 women and 22 men). Thirty-four patients received eyebrow hair transplantation, 73 underwent female hairline correction surgery, nine patients underwent sideburn reconstruction, two were treated for female pattern hair loss, and 19 were treated for male pattern baldness (MPB). Four of the patients with MPB also underwent eyebrow transplant surgery. Of the patients with MPB, 17 (89%) had Norwood type III baldness, and two (11%) had type IV hair loss. The mean number of grafts required was 292 for eyebrow transplantation, 1,214 for female hairline correction, 251 for sideburn reconstruction, 1,344 for female pattern hair loss, and 1,567 for MPB. The mean follicle transection rate was 9.2%, and the mean calculated number of follicles per graft achieved was 2.23.

conclusionThis long hair FUE method introduced by the authors is an excellent surgical method when performed by surgeons with sufficient skill and expertise.
