Learning curve in robotic inguinal hernia repair: a systematic review and meta-analysis.

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
introductionThis study aims to perform a systematic review and meta-analysis to assess the learning curve in robotic transabdominal preperitoneal (rTAPP) inguinal hernia repair in adult patients, emphasizing the number of procedures associated with improved operative efficiency and the evolution of operative performance over time. MATERIALS AND
methodsA systematic review was conducted following PRISMA guidelines. A comprehensive search of PubMed/MEDLINE, Embase, Cochrane Library, Web of Science, Lilacs and SciELO was performed through March 2026, including cohort studies on adult patients undergoing elective robotic inguinal hernia repairs. Studies were eligible for quantitative synthesis if operative time was reported across distinct learning phases. Operative time between phases was pooled using a random-effects model, and mean differences (MD) with 95% confidence intervals (CI) were calculated. Heterogeneity was assessed using the I² statistic.
results622 articles were screened, of which 13 met the inclusion criteria and were included in the systematic review. All studies evaluated learning curves in multiport rTAPP inguinal hernia repair. A total of 1,770 patients were included, of whom 1,465 were male (82.8%), with a mean BMI was 25.3 kg/m
conclusionsAmong studies using operative-time-based CUSUM analyses, a median threshold of 32 cases was associated with improved operative efficiency in rTAPP, as reflected by reduced operative time. Progression beyond this initial learning phase is consistently associated with improved operative efficiency, including a pooled reduction of 17.02 min in operative time. Future studies should incorporate competency-based assessments and clinically meaningful outcomes to provide a more comprehensive evaluation of surgical proficiency.
