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

The purpose of this study is to compare trifecta achievement between single-port (SP) and multi-port (MP) robotic cohorts at a high-volume institution and to assess the impact of nephrometry score and demographic factors on these outcomes. Our institution's IRB-approved, prospective renal cancer database was used to identify 753 patients with renal cell carcinoma (RCC) who underwent robot-assisted partial nephrectomy (RAPN) from 2017 to 2025. Patients were stratified into cohorts based on SP and MP RAPN approach. Trifecta rates for each group were compared between the cohorts using complete-case and multiple imputation data sets. Multiple logistic regression models assessed associations between trifecta achievement and surgical approach, age, sex, body mass index (BMI), nephrometry score, and tumor size. Alternatively, trifecta rates were stratified by the nephrometry score and the common odds ratio and heterogeneity was tested across the nephrometry score strata with Cochran-Mantel-Haenszel and Breslow-Day tests. Trifecta achievement did not differ significantly between the SP (N = 102; 76%) and MP (N = 494; 80%) groups (p = 0.46). Trifecta achievement odds were not significantly influenced by surgical platform choice (p = 0.052). Among the factors we analyzed, only nephrometry score was significantly associated with trifecta achievement, while surgical approach showed no significant association. We conclude that, for high-volume surgeons with experience using SP, there is no statistically significant difference in trifecta achievement between SP and MP RAPN after adjusting for age, sex, BMI, tumor size and nephrometry score. Limitations of this study include complete-case restriction and baseline characteristic imbalances between SP and MP cohorts.
