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
objectivesThe aim of this study was to investigate the feasibility and safety of retrograde puncture for trocar placement for the establishment of the preperitoneal space in laparoscopic total extraperitoneal repair (TEP) for groin hernias.
methodsA retrospective analysis of the clinical data of 1388 patients who underwent TEP surgery for a groin hernia at the General Hospital of Northern Theater Command of the Chinese People's Liberation Army (hereinafter referred to as the General Hospital of Northern Theater Command) from August 2013 to August 2023 was conducted. The feasibility and safety of retrograde puncture for trocar placement for the establishment of the preperitoneal space were examined.
resultsAll 1388 operations were successful, with no conversion to open surgery. The mean time for unilateral placement of the Trocars was 6.36 ± 2.32 min. The mean time for unilateral hernia surgery was 42.73 ± 10.33 min, and the mean time for bilateral hernia surgery was 73.11 ± 20.31 min. Peritoneal injuries were observed in 8 patients (0.58%), but there were no abdominal organ injuries. Two patients (0.14%) had inferior epigastric vascular injuries, and 16 patients (1.15%) experienced muscle hemorrhage during retrograde puncture. Twenty-five patients (1.80%) had postoperative local hematomas of the abdominal wall, and 37 patients (2.67%) had subcutaneous emphysema. Sixty-four patients (4.61%) experienced seroma retention, and 13 patients (0.94%) experienced urinary retention. The postoperative follow-up period ranged from 3 to 124 months, with a median follow-up time of 66 months. None of the patients experienced recurrence, persistent pain, localized foreign body sensation, mesh infection, or incision infection.
conclusionsThe retrograde puncture method for placing trocars to establish the preperitoneal space in laparoscopic TEP surgery for groin hernias is feasible and safe.
