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
purposeThis study aims to compare the safety and efficacy of robot-assisted partial nephrectomy (RAPN) and robot-assisted radical prostatectomy (RARP) using the Chinese surgical systems KangDuo-SR-2000 (KD-SR-2000) and EDGE MP1000 (MP1000) versus the Da Vinci Xi (DV-Xi) system, to explore viable alternative options to DV-Xi.
methodsThis prospective, single-center, non-randomized clinical trial enrolled 261 patients who underwent RAPN or RARP from August 2023 to June 2024. All surgeries were performed by 3 surgeons. For RAPN, the primary outcome included surgical success, positive surgical margin (PSM), warm ischemia time (WIT) and conversion to open or laparoscopic surgery. The secondary outcome was estimated glomerular filtration rate (eGFR). For RARP, the primary outcome was surgical success without conversion to open or laparoscopic surgery, and the secondary outcomes included PSM and urinary continence recovery at 4 weeks post-catheter removal.
resultsBaseline demographics were comparable across the KD-SR-2000 group (n = 88), EDGE MP1000 group (n = 59) and DV-Xi group (n = 114). No significant differences observed in primary and secondary outcomes. However, operation time and suture time per stitch were longer in Chinese surgical systems for both RAPN and RARP compared to DV-Xi, and estimated blood loss (EBL) is higher in RAPN. Subgroup analyses indicated that performance differences were primarily attributed to the KD-SR-2000, with no significant differences observed between the MP1000 and DV-Xi. No severe complications (Clavien-Dindo grade ≥ 3) reported in any group.
conclusionsChinese surgical systems provide a viable alternative, demonstrating non-inferiority compared to DV-Xi. TRIAL REGISTRATION NUMBER: ChiCTR2300074914; Registration Date: 2023-08-21.
