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

introductionIn recent surgical literature, gender-specific differences in the outcome of hernia surgery has been analyzed. We already know that female patients are at higher risk to develop chronic postoperative pain after inguinal, incisional, and umbilical hernia surgery. In this study, we evaluated the impact of gender on the outcome after epigastric hernia surgery.

methodsA covariable-adjusted matched-paired analysis with data derived from the Herniamed registry was performed. In total of 15,925 patients with 1-year follow-up data were included in the study. Propensity score matching was performed for the 7786 female (48.9%) and 8139 male (51.1%) patients, creating 6350 pairs (81.6%).

resultsMatched-paired analysis revealed a significant disadvantage for female patients for pain on exertion (12.1% vs. 7.6%; p < 0.001) compared to male patients. The same effect was demonstrated for pain at rest (6.2% in female patients vs. 4.1% in male patients; p < 0.001) and pain requiring treatment (4.6% in female patients vs. 3.1% in male patients; p < 0.001). All other outcome parameters showed no significant differences between female and male patients.

conclusionsFemale patients are at a higher risk for chronic pain after elective epigastric hernia repairs compared to the male patient population. These results complete findings of previous studies showing the same effect in inguinal, umbilical, and incisional hernia repair.
