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
backgroundRobot-assisted transabdominal preperitoneal inguinal hernia repair (rTAPP-IHR) is a safe and feasible approach for hernias of varying etiology. We aim to present a single surgeon's learning curve (LC) of this technique based on operative times, while accounting for bilaterality and complexity.
methodsThis is a retrospective cohort analysis of patients who underwent rTAPP-IHR over a period of 5 years. Patients who underwent primary, recurrent, and complex (previous posterior repair, previous prostatectomy, scrotal, incarcerated) repairs were included. Cumulative and risk-adjusted cumulative sum analyses (CUSUM and RA-CUSUM) were used to depict the evolution of skin-to-skin times and complications/surgical site events (SSEs) with time, respectively.
resultsA total of 371 patients were included in the study. Mean skin-to-skin times were stratified according to four subgroups: unilateral non-complex (46.8 min), unilateral complex (63.2 min), bilateral non-complex (70.9 min), and bilateral complex (102 min). A CUSUM-LC was then plotted using each procedures difference in operative time from its subgroup mean. The peak of the plot occurred at case number 138, which was used as a transition between 'early' and 'late' phases. The average operative time for the late phase was 15.9 min shorter than the early phase (p < 0.001). The RA-CUSUM, plotted using the weight of case complexity and unilateral/bilateral status, also showed decreasing SSE rates after the completion of 138 cases (early phase: 8.8% vs. late phase: 2.2%, p = 0.008). Overall complication rates did not differ significantly between the two phases.
conclusionsOur study shows that regardless of bilateral or complex status, rTAPP operative times and SSE rates gradually decreased after completing 138 procedures. Previous laparoscopic experience, robotic team efficiency, and surgical knowledge are important considerations for a surgeon's LC.
