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

backgroundTo present the complications of free-flap phalloplasty in three-staged female-to-male transgender surgery.

methodsThis retrospective study included patients who underwent a three-staged free-flap phalloplasty for female-to-male transgender surgery between January 1988 and December 2013. Data regarding demographics, operative techniques, and complications were collected and analyzed.

resultsA total of 101 patients with a mean age of 30.2 years were included. Phalloplasty with traditional free forearm tube-in-tube fasciocutaneous flap was performed in 25 (24.8%) patients, free forearm fasciocutaneous flap with vaginal mucosa for a prefabricated urethra in 30 (29.7%) patients, free radial forearm osteocutaneous flap with vaginal mucosa for a prefabricated urethra in 22 (21.8%) patients, and free fibula osteocutaneous flap with vaginal mucosa for a prefabricated urethra in 24 (23.8%) patients. Complication rates of partial flap loss, urethrocutaneous fistula, urethral stricture, and hair or stone formation were 12.9%, 49.5%, 24.8%, and 5.0%, respectively. Patients receiving fibula osteocutaneous flap phalloplasty had the lowest overall complication rate (33.3%), followed by those with radial forearm osteocutaneous flap (40.9%), forearm fasciocutaneous flap (43.3%), and forearm tube-in-tube fasciocutaneous flap (80.0%). Forearm tube-in-tube fasciocutaneous flap procedure was associated with significantly higher rates of overall complications (p = 0.05), urethrocutaneous fistula (p = 0.005), and hair or stone formation (p = 0.002) compared with the other three types of procedures. Rates of all complications did not significantly differ among fibula osteocutaneous flap, radial forearm osteocutaneous flap, and forearm fasciocutaneous flap procedures.

conclusionIn free-flap phalloplasty for female-to-male transgender surgery, utilization of free fibula osteocutaneous flap with vaginal mucosa for a prefabricated urethra resulted in the lowest complication rate. Further comparisons among different procedures of phalloplasty are warranted.
