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
Background: Small renal masses (SRMs) (≤4 cm) now comprising >70% of newly detected renal cancers. Nephron-sparing partial nephrectomy (PN) is guideline-recommended, and robotic surgery is becoming increasingly popular. However, the existing single-port (SP) platform is constrained by economic reasons and regional regulatory barriers. This report presents the first two clinical cases of transumbilical SP robotic-assisted PN (SP-RAPN) using the domestically developed Shurui Case Description: Two patients (a 65-year-old woman and a 56-year-old man) with SRMs underwent transumbilical SP-RAPN via a 3 cm peri-umbilical incision within the natural skin crease. The RENAL (radius, exophytic, nearness, anterior/posterior, and location) nephrometry scores of these two cases were 5 and 6. Intraoperative data, including docking time, operative duration, estimated blood loss (EBL), warm ischemia time (WIT), and postoperative pain scores, were prospectively recorded. Both procedures were successfully completed without conversion to open or multi-port surgery. Docking time was 4 minutes in both cases; console time was 112 and 135 minutes; EBL was 100 and 50 mL; WIT was 24 and 21 minutes; and postoperative length of stay was 5 and 6 days, respectively. No Clavien-Dindo grade ≥ II complications occurred. Postoperative pain intensity assessed with the numeric rating scale (NRS) was ≤2/10 at 24 hours and decreased to 0-1/10 by postoperative day 2. Pathological report of renal clear cell carcinoma [World Health Organization (WHO) grade 2], with negative margins in both cases. Conclusions: Early outcome shows that transumbilical SP-RAPN using the Shurui
