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

introductionWe aimed to evaluate the impact of surgical mentorship on case outcomes and learning curves of early-career surgeons performing pediatric open pyeloplasty.

methodsUsing an institutionally maintained prospective case log, we retrospectively analyzed all open pyeloplasty cases consecutively performed by an index junior academic surgeon under the mentorship of a senior surgeon between April 2020 and May 2023. The mentor was available for all cases and scrubbed in for early cases, with decreasing direct involvement over time. The data collected included case characteristics, operative times, followup durations, and surgical complications within a two-year postoperative period. A cumulative sum (CUSUM) analysis was employed to identify peaks, plateaus, and trends for complications (defined as Clavien-Dindo classification ≥3b) and operative time.

resultsWe analyzed 54 open pyeloplasty cases performed under surgical mentorship and categorized them into four phases using CUSUM analysis. Based on this, the junior surgeon reached the competency-proficiency phase between the 12th and 26th case, demonstrating consistent technical skill development, reduced operative times, and satisfactory outcomes under mentorship. In the case-mix phase (45

conclusionsThis analysis demonstrated that surgical mentorship for junior academic surgeons facilitates early technical proficiency in pediatric open pyeloplasty, enabling them to safely achieve comparable outcomes early in their careers. These findings suggest that mentorship is key to ensuring satisfactory surgical outcomes during the initial stages of a surgeon's learning curve.
