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

Introduction and Objective: This study aims to evaluate the learning curve and perioperative outcomes of single-port extraperitoneal robotic radical prostatectomy (SP-EP-RARP) performed by a single surgeon at a high-volume academic institution. Methods: A retrospective review of a prospectively maintained database was conducted for patients who underwent SP-EP-RARP from September 2023 to August 2025. Key metrics included operative time, estimated blood loss, conversion rate, nerve-sparing status, pathological margin status and continence (0-1 pad for safety), and 30-day complication rate. Descriptive statistics were used, and outcomes were analysed chronologically to assess for trends suggesting a learning curve. Results: The cohort included 53 patients who underwent extraperitoneal SP-EP-RARP. Median operative time was 213 min (IQR: 145-281). Median estimated blood loss was 100 mL (IQR: 75-125). Nerve-sparing was attempted in 75.5% of cases. No assist Conclusion: SP-EP-RARP can be safely implemented by a newly graduated fellowship-trained robotic surgeon with acceptable oncologic and functional outcomes. Initial learning can be estimated at approximately 25-30 cases.
