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

backgroudRecently, laparoscopic percutaneous extraperitoneal closure (LPEC) has gained increased popularity for pediatric inguinal hernia repair. To improve cosmesis, we developed single incision LPEC (SILPEC). The aim of this study was to assess the safety and feasibility of SILPEC compared with traditional open repair (OR).

methodsThis was a single-center retrospective cohort study of 2028 children who underwent inguinal hernia repair between April 2005 and August 2014. Nine hundred and ninety-five patients underwent OR and 1033 patients underwent SILPEC. Medical records were reviewed with respect to operative time, recurrence, incidence of contralateral metachronous inguinal hernia (CMIH), and complications. Patient satisfaction with cosmetic result was also investigated using questionnaires sent by mail.

resultsAll SILPEC procedures were completed without conversion. Operative time was longer in the SILPEC group than in the OR group for both unilateral and bilateral surgery regardless of sex (unilateral male: p = 0.0006, unilateral female: p < 0.0001, bilateral male: p < 0.0001, bilateral female: p < 0.0001). There was no statistically significant difference in recurrence rate (p = 0.43). The incidence of CMIH was significantly higher in the OR than in the SILPEC group (p < 0.0001). No postoperative testicular atrophy was found in either group. There was no statistically significant difference in ascending testis (p = 0.09), but the frequency of surgical site infection was higher in the SILPEC than in the OR group (p = 0.0013). According to the questionnaire, operative scar was more invisible in the SILPEC than in the OR group (p < 0.0001), but both procedures had equally high levels of satisfaction for cosmetic results (p = 0.58).

conclusionSILPEC proved to be a safe and feasible procedure compared with OR with an equally low recurrence rate, more effectiveness for preventing CMIH, and more invisible scar.
