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

backgroundThe enhanced Totally Extra-Peritoneal (eTEP) technique is a novel minimally invasive approach to inguinal hernia repair that involves entry into the retro-rectus space and dissection of preperitoneal spaces. Aim of this study is to compare two methods for creating the preperitoneal space: optical trocar dissection (Group A) and balloon trocar dissection (Group B). MATERIALS AND

methodsA prospective, single-blinded, interventional study was conducted with 116 patients, randomized into two groups (58 in each group) undergoing eTEP inguinal hernia repair at SRM Medical College Hospital, India. Key outcomes assessed included the duration of surgery, intraoperative complications, postoperative pain, and postoperative occurences such as seroma and hematoma.

resultsThe study found that balloon trocar dissection resulted in significantly shorter surgery duration (mean 62 min vs. 75 min, p<0.001) and quicker preperitoneal space creation (13 min vs. 19 min, p<0.0001). Balloon dissection also showed fewer incidents of peritoneal breaches (0% vs. 10.34%, p<0.002), lower postoperative pain scores, and a lower incidence of seroma and hematoma formation (1.72% vs. 17.24%, p<0.004).

conclusionThese findings suggest that balloon trocar dissection is a safer, more efficient method for eTEP inguinal hernia repair, offering a smoother learning curve for surgeons, especially during the early stages of the procedure.
