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

Background and objective: Postoperative bleeding in robot-assisted partial nephrectomy (RAPN) can result in a major complication. This study aims to identify factors associated with postoperative bleeding requiring an intervention (PBRI) as a major complication and predictors of blood transfusions as a minor complication. Methods: This study is a multicentric, retrospective analysis of 3726 RAPN cases. Separate comparative analysis was performed between: (1) patients with PBRI versus those without PBRI and (2) patients with blood transfusion versus those without blood transfusion. Two independent multivariable logistic regression analyses were performed to identify predictors for each endpoint. Key findings and limitations: PBRI occurred in 1.9% of patients and transfusion in 4.6%. Main interventions were angiography (49%) and operative revision (39%), with nephrectomy in 7.1% of patients. In both complication groups, patients were older (both Conclusion and clinical implications: Most hemorrhagic complications after RAPN can be managed with kidney-preserving, multidisciplinary approaches. However, whether preoperative anemia correction is associated with improved outcomes should be investigated in future studies.
