The impact of nerve management on the risk for persistent postoperative pain one year after open anterior mesh inguinal hernia repair.

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.
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
purposePersistent postoperative pain is a major challenge in inguinal hernia surgery. However, the impact of intraoperative nerve management on postoperative pain is poorly understood. The aim was to evaluate how management of the three inguinal nerves during anterior mesh repair of inguinal hernia affects the risk for persistent postoperative pain.
methodsCohort study based on data from the Swedish Hernia Register (SHR) concerning management of the three inguinal nerves. Adult patients with an open anterior mesh repair between 2012 and 2017 and who had responded to a patient-reported outcome measure (PROM) questionnaire one year after surgery were included in the study.
resultsOut of eligible patients, 34,115 (69%) responded to the PROM questionnaire. Of these, 25.9% reported pain that could not be ignored and 15.7% reported pain interfering with daily activities one year after surgery. Identifying and/or preserving any of the three groin nerves was not seen to have a significant impact on the risk for persistent groin pain in multivariable ordinal regression analysis adjusted for type of anaesthesia, gender, age and emergency surgery.
conclusionIn a setting where the nerves are handled according to the surgeon's intraoperative judgement focusing on identifying and/or preserving the nerves, there was no association between intraoperative management of the three inguinal nerves and the risk for persistent postoperative pain one year after surgery. While careful tissue handling is crucial to the avoidance of postoperative pain, pragmatic nerve resection did not increase the risk for persistent pain one year after surgery.
