1 · What the graph read from 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.

2 · The registry

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

purposeWe compared surgical outcomes between robot-assisted laparoscopic partial nephrectomy (RAPN) and open partial nephrectomy (OPN) by using volumetric analysis in a propensity score-matched analysis.

methodsWe analyzed the records of 279 patients with normal contralateral kidneys who underwent RAPN or OPN for T1 renal tumors between 2012 and 2014. Volumetric studies to assess the vascularized parenchymal volume of the operated kidney were performed 2 months preoperatively and 6 months postoperatively. Patient data, including age, body mass index, presence of hypertension and/or diabetes mellitus, American Society of Anesthesiologists score, tumor size, preoperative estimated glomerular filtration rate, and tumor complexity using the renal nephrometry score, were matched 1:1 using propensity score matching between groups.

resultsThis cohort included 100 patients who underwent RAPN and 179 who underwent OPN. After matching, 48 patients were included in each group. Mean tumor diameter was 31 mm, and about 14 % were high-complexity tumors (RENAL score 10-12). The RAPN and OPN groups showed no significant differences in the rate of preservation of global renal function (95 vs. 92 %) and parenchymal volume of the operated kidney (84 vs. 79 %). Similarly, urological complications did not significantly differ between groups. Surgical margins were negative in all tumors. Patients who underwent RAPN had lower estimated blood loss (p < 0.0001) and shorter postoperative length of hospital stay (p < 0.0001) than those who underwent OPN.

conclusionRAPN can offer acceptable surgical outcomes and precision, compared to OPN, with decreased estimated blood loss and hospital stay.
