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

backgroundSeroma/hematoma formation is the most common postoperative complication after laparoscopic inguinal hernia repair. The occurrence of seroma/hematoma remains unclear. The aim of this study was to determine the risk factors for seroma/hematoma formation after transabdominal preperitoneal patch plasty (TAPP).

methodsThe study enrolled 359 groin hernia patients treated by TAPP at Kumamoto Medical Center between 2014 and 2019. The primary outcome was risk factors for postoperative seroma/hematoma formation after TAPP. The secondary outcomes included recurrence of hernia, postoperative complications, and hospital stay.

resultsAmong the 359 patients, the incidence rate of seroma/hematoma was 16% (n = 69 patients), and the recurrence rate was 0.3% (n = 1 patient, both sides). In total, there were 452 lesions. Japan Hernia Society (JHS) type II was present in 23% (n = 106) of the total cases but was significantly more common in the postoperative seroma/hematoma group (40%; P = 0.0082). Meanwhile, JHS type I-3 comprised 27% of the total JHS type I group but was significantly higher in the postoperative seroma/hematoma JHS type I group (40%; P = 0.016). Compared with JHS type I, the multivariable odds ratio for postoperative seroma/hematoma formation in JHS type II was 2.77 (95% CI 1.54-4.95). Compared with JHS grade 1/2, the multivariable odds ratio for postoperative seroma/hematoma formation in JHS grade 3 was 2.27 (95% CI 1.28-4.03).

conclusionsInternal inguinal hernia and hernia size ≥ 3 cm were considered risk factors for postoperative seroma/hematoma formation after TAPP.
