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

backgroundThe optimal laparoscopic approach for bilateral inguinal hernia repair is unclear. The 2 primary methods are totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) approaches. We conducted a systematic review and meta-analysis to compare surgical outcomes of TEP and TAPP for bilateral inguinal hernia repair.

methodsPubMed, EMBASE, and CENTRAL databases were searched through April 15, 2025. Studies comparing TEP and TAPP in adults with bilateral inguinal hernias were included. Outcomes assessed included hernia recurrence, pain scores, length of hospital stay (LOS), operation time, return to activities of daily living, and complications. Odds ratios (ORs) and standardized mean differences (SMDs) were pooled using fixed or random effects models.

resultsThree randomized controlled trials (RCTs) and 4 retrospective studies with a total of 1164 patients were included in the analysis. Hernia recurrence was significantly lower with TAPP compared to TEP (pooled OR 0.27, 95% confidence interval [CI] 0.11-0.67; I

conclusionsTAPP is associated with lower recurrence risk and earlier recovery compared to TEP. Further large-scale, high-quality trials are needed to validate these findings.
