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

Objective: To evaluate the effect of clamping multiple renal arteries on postoperative renal function in patients undergoing robot-assisted partial nephrectomy (RAPN). Methods: A retrospective review of 694 patients who underwent RAPN for renal tumors between March 2016 and June 2023 was conducted. The patients were categorized into single and multiple clamp cohorts. Baseline differences were minimized using 1:1 propensity score matching. Renal function was evaluated using estimated glomerular filtration rate (eGFR) at 7 days and 1, 3, and 12 months postoperatively. Additionally, acute kidney injury (AKI), chronic kidney disease (CKD) progression, and dialysis requirements were evaluated. Statistical significance was defined as p < 0.05. Results: After matching, 27 patients were included in each group. There were no significant differences in perioperative outcomes, including warm ischemia time, trifecta achievement, and surgical margin status. Despite a longer operative time in the multiple clamp group, no adverse effects on renal function were observed. There were no significant group differences in the eGFR at any time point or in the rates of AKI, CKD progression, or dialysis requirement. Conclusion: Clamping of multiple renal arteries during RAPN did not appear to negatively affect short- or long-term postoperative renal function. Multiple clamping may be an acceptable technique for achieving a bloodless surgical field when necessary.
