Performance and safety of Kangduo surgical robot versus da Vinci robotic system for urologic surgeries.
Article in Langenbeck's archives of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
objectiveKangduo (KD) surgical robot is a novel robotic system in China, and some animal experiments and single-arm clinical trials have indicated its effectiveness, feasibility, and safety for urologic surgeries. This study intended to compare the performance and safety of the KD surgical robot with the da Vinci (DV) robotic system in patients who received urologic surgeries.
methodsA total of 201 patients who received urologic surgeries were divided into the KD group (N = 60) and the DV group (N = 141) according to the actual surgical methods.
resultsThe median (range) operation time [180.0 (30.0-540.0) minutes vs. 130.0 (70.0-360.0) minutes] (P < 0.001) and indwelling time of abdominal drainage tube [5.0 (2.0-14.0) days vs. 3.0 (2.0-18.0) days] (P < 0.001) were longer, but the intraoperative blood loss [50.0 (10.0-200.0) mL vs. 50.0 (10.0-400.0) mL] (P < 0.001) was less in the KD group than the DV group. The median values of white blood cells at the 1st (P = 0.032) and 3rd (P = 0.022) day after surgery were decreased in the KD group compared to the DV group. The incidence of infection (11.7% vs. 29.1%) (P = 0.008) and fever (15.0% vs. 30.5%) (P = 0.023) was lower in the KD group compared to the DV group. Postoperative and follow-up parameters, including time of urinary incontinence improvement, administration of hemostatic, pain numeric rating scale score, Barthel's index score, and patient satisfaction, were not different between the two groups (all P > 0.05).
conclusionThe KD surgical robot unveils satisfactory surgical performance compared to the DV robotic system in patients receiving urologic surgeries.
