Chronic pain after two laparoendoscopic inguinal hernia repairs compared with laparoendoscopic repair followed by the Lichtenstein repair: an international questionnaire study.
Article in Surgical endoscopy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe best repair of a recurrent inguinal hernia after primary laparoendoscopic repair is debatable. The aim was to assess chronic pain after two laparoendoscopic repairs in the same groin compared with Lichtenstein reoperation preceded by a laparoendoscopic repair.
methodsThis cohort study included adult patients who had received two laparoendoscopic repairs (Lap-Lap) or a laparoendoscopic repair followed by the Lichtenstein repair (Lap-Lich). Eligible patients were identified in the Danish and the Swedish hernia databases. Lap-Lap was matched 1:3 with Lap-Lich, and patients were sent validated questionnaires. The primary outcome was the proportion with chronic pain-related functional impairment, compared between the two groups. Secondary outcomes included chronic pain during various activities.
resultsIn total, 74% (546 patients) responded to the questionnaires with a median follow-up since the second repair of 4.9 years (0.9-21.9 years). Regarding the primary outcome, 21% in Lap-Lap and Lap-Lich had chronic pain-related functional impairment of daily activities (p = 0.94). More patients in Lap-Lap compared with Lap-Lich reported pain ≥ 20 mm measured by the visual analog scale, 11% versus 5%, p = 0.04. However, there was no difference in the median VAS score or in the vast majority of the remaining secondary outcomes.
conclusionsThere was no overall difference in chronic pain between patients who had received Lap-Lap compared with Lap-Lich. Choice of operative strategy for the second repair should, therefore, not be based on risk of chronic pain.
