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

purposeA large proportion of patients experience chronic post-surgical pain (CPSP) following inguinal hernia repair surgery. The aim of this study was to investigate the predictive risk factors and protective factors for CPSP following inguinal hernia surgery.

methodsAfter institutional ethics approval was obtained, we conducted a retrospective observational case-control study including a total of 236 adult patients undergoing elective inguinal hernia repair at a single tertiary medical center from 2014 to 2015. Preoperative and postoperative variables were collected from electronic medical records. Binary logistic analysis was used to determine the association between CPSP and clinical factors and built a CPSP risk model.

resultsThe incidence of CPSP was 14.4%. Bilateral inguinal hernia repair (OR 4.44; 95% CI 1.62 to 12.17; p = 0.004), preoperative pain (OR 2.57; 95% CI 1.14 to 5.79; p = 0.023), preoperative anxiety (OR 1.05; 95% CI 1.01 to 1.09; p = 0.018), and relatively high intensity of acute pain at 1 week after the surgery (OR 1.40; 95% CI 1.03 to 1.91; p = 0.031) were the risk factors for CPSP while low-dose ketamine at anesthesia induction (OR 0.42; 95% CI 0.18 to 0.98; p = 0.044) was the protective factor for CPSP in patients undergoing inguinal hernia repair.

conclusionsThese results indicated that bilateral inguinal hernia repair, preoperative pain, preoperative anxiety, and acute pain at 1 week after the surgery were the independent risk factors for CPSP while low-dose ketamine was the protective factor. These findings may assist with primary prevention by allowing clinicians to screen for individuals with the risk of CPSP.
