Robot-assisted versus laparoscopic partial nephrectomy for localized renal tumors: a systematic review and meta-analysis of oncological, perioperative, and renal functional outcomes.
Synthesis 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
To update the comparative evidence on robot-assisted partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) for patients with cT1-cT2 renal tumors, with emphasis on cancer control, perioperative recovery, and postoperative kidney function. Four databases were queried for English-language comparative studies published between January 30, 2016 and March 1, 2026. Eligible reports enrolled adults with localized renal tumors treated with RAPN or LPN and provided extractable oncological, perioperative, or renal functional data. Two reviewers performed study selection, extraction, and quality appraisal. Treatment effects were calculated as odds ratios for binary variables and mean differences for continuous variables. Heterogeneity, sensitivity, small-study effects, subgroup patterns, and evidence certainty were explored where data allowed. Twenty-two studies with 6,202 participants were analyzed. Surgical margin positivity and recurrence did not differ materially between RAPN and LPN (OR 0.83, 95% CI 0.49-1.42; and OR 1.32, 95% CI 0.43-4.02, respectively). RAPN was associated with fewer overall complications (OR 0.72, 95% CI 0.55-0.93), lower transfusion requirement (OR 0.49, 95% CI 0.25-0.94), less blood loss (MD -27.88 mL, 95% CI -40.28 to -15.47), shorter warm ischemia (MD -3.54 min, 95% CI -4.65 to -2.44), smaller eGFR reduction (MD -3.05 mL/min/1.73 m
