Comparing incisional hernia risk between single-port and multiport robot-assisted partial nephrectomy: a retrospective analysis.
Article in Journal of robotic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Incisional hernia (IH) is a postoperative complication. No studies have investigated IH rates after Single Port (SP) partial nephrectomy (RAPN). This study aims to evaluate IH incidence after SP RAPN and to compare factors influencing IH in SP versus Multiport (MP) RAPN. Patients undergoing MP and SP RAPN were retrospectively included. Patients with less than 6 months follow-up, those undergoing concomitant procedures, converted to open or radical nephrectomy or with prior IH, were excluded from the study. A total of 279 patients (MP: 158(56.6%); SP: 121(43.4%)) were collected. IH developed in 12 patients (MP: 7 (4.4%); SP: 5 (4.1%)). In MP group, IH cases were more frequently associated with previous abdominal surgery (6 (85.7) vs. 22 (14.6); p < 0.001), higher BMI (36.4 (12.6) vs. 30.4 (9.25); p = 0.048) and presented with larger tumor size (4.0 (0.9) vs. 3.1 (1.6); p = 0.007). MP IH patients had larger tumors than those in SP group (4.0(0.9) vs. 2.8(0.4); p = 0.006). Stratified multivariable logistic regression demonstrated that previous abdominal surgery remained significantly associated with IH in the MP group (Odds ratio: 2.36; 95%CI: 1.06, 3.66; p < 0.001), while BMI was independently associated with IH only in MP RAPN (Odds ratio: 1.18; 95% CI: 1.02, 1.49; p = 0.028). IH rates after SP RAPN were comparable to those observed after MP RAPN. Established risk factors appeared to have a stronger impact in MP RAPN, while a lower observed incidence of IH was noted in selected SP subgroups, including those undergoing a retroperitoneal approach.
