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

backgroundThis study aimed to compare the results of open and laparoscopic preperitoneal groin hernia repair.

methodsThis study included patients with groin hernias who underwent open or laparoscopic preperitoneal herniorrhaphy in our department from October 2016 to December 2019 following the inclusion and exclusion criteria. Baseline characteristics, operative variables, recurrence, intraoperative, short-term, and long-term postoperative complications were recorded and further analyzed.

resultsAmong the 1251 patients (290 open and 948 laparoscopic, 13 bilateral hernias found during laparoscopic operation were withdrawn), 94.83% completed a median follow-up of 23 (8-52) months. The overall recurrence rate was 0.60%, and no significant difference was observed between the two approaches (p = 0.775). The overall complication rate of the laparoscopic approach was lower than that of the open approach (9.60 vs. 13.79%, p = 0.042), whereas the life-threatening complication rates were similar (1.38 vs. 0.63%, p = 0.214). The operation time was similar between the two approaches, but the laparoscopic approach resulted in significantly lower incidence rates of wound infection and chronic pain, lower visual analog scale scores, and faster recovery than the open approach, but the hospitalization cost was higher. After a propensity score-matched (PSM) analysis, postoperative chronic pain was proved no significant difference between the two groups.

conclusionsBoth open and laparoscopic procedures are safe and effective for groin hernia preperitoneal herniorrhaphy, with low incidence rates of life-threatening complications and recurrence. The laparoscopic approach is superior in terms of lower incidence rates of infection and faster recovery but costs more than the open approach.
