Laparoscopic versus open repair for inguinal hernia in children: a retrospective cohort study.
Article in Surgery today, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05092425 (Analysis of Risk Factors for Children With Heterochronous Indirect Hernia), which is not on this map. Cited by 14 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.

Abstract
purposeWe compared the outcomes of laparoscopic surgery (LS) with those of open surgery (OS) for unilateral and bilateral pediatric inguinal hernia.
methodsUsing a nationwide claim-based database in Japan, we analyzed data from children younger than 15 years old, who underwent inguinal hernia repair between January 2005 and December 2017. Patient characteristics, incidence of reoperation, postoperative complications, length of hospital stay, and duration of anesthesia were compared between LS and OS for unilateral and bilateral hernia.
resultsAmong 5554 patients, 2057 underwent LS (unilateral 1095, bilateral 962) and 3497 underwent OS (unilateral 3177, bilateral 320). The incidence of recurrence was not significantly different between OS and LS (unilateral: OS 0.2% vs. LS 0.3%, p = 0.44, bilateral: OS 0.6% vs. LS 0.6%, p = 1.00). The incidence of metachronous hernias was significantly higher in the OS group than in the LS group (4.8% vs. 1.0%, p < 0.001). The surgical site infection rate was significantly lower after OS than after LS for unilateral surgeries (0.9% vs. 2.2%, p = 0.002). There was no difference between OS and LS in the length of hospital stay.
conclusionBoth OS and LS had a low incidence of recurrence in children; however, the incidence of metachronous hernias was lower for LS, which may influence operative technique decisions.
