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

objectiveThe experience of performing robot-assisted partial nephrectomy (RAPN) is associated with better surgical outcomes. However, surgeon's generation may impact surgical outcomes. We evaluated the perioperative outcomes of RAPN between first- and second-generation surgeons according to the surgeon's experience.

methodsThis study included 529 patients who underwent RAPN for renal cell carcinoma from January 2013 to November 2018. Four specific surgeons performed the surgery. According to the surgeon's generation, the patients were divided into two groups: first-generation and second-generation. To reflect the learning curve of RAPN, the surgical outcomes of each case (1-50, 51-100, 101-150) were evaluated between these groups.

resultsBetween 1 to 50 cases and 101-150 cases, no significant differences in patient characteristics were observed between the two generations. Between 51-100 cases, age at surgery was significantly younger in the first-generation than in the second-generation group (58 years vs. 64 years, p = 0.04). The second-generation group had a shorter operation time in cases 1-50 (169 min vs. 188 min, p = 0.0001), 51-100 (145 min vs. 169 min, p = 0.008), and 101-150 (142 min vs. 165 min, p = 0.009), than the first-generation group. Although shorter WIT and higher trifecta achievement were observed in the second-generation group than in the first-generation group between 1-50 cases, the difference was not noted between 51-100 cases and 101-150 cases.

conclusionPatients operated by second-generation surgeons had better surgical outcomes than first-generation surgeons, especially during the early experience period, which might result from their assistance experience, sophisticated surgical procedures refined by the first-generation, and the first-generation surgeon's introduction.
