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

purposeTo compare the short-term outcomes of robotic distal pancreatectomy (RDP) and laparoscopic distal pancreatectomy (LDP), with a particular focus on the actual completion rates of spleen and splenic vessels preservation preoperatively.

methodsFifty-two RDP and 87 LDP procedures performed between 2014 and 2024 were retrospectively analyzed.

resultsThe operative time was significantly longer for RDP than for LDP (median 407 min vs. 320 min, p < 0.0001), whereas the intraoperative blood loss was significantly lower (median 70 mL vs. 100 mL, p = 0.011). The rate of conversion to open surgery was also lower for RDP (2% vs. 10%, p = 0.042). The spleen preservation rate, defined as the proportion of cases in which spleen preservation was achieved preoperatively, was 100% (12/12) and 92% (23/25) in the RDP and LDP groups, respectively (p = 0.203). The splenic vessels preservation rate was significantly higher with RDP (100% [10/10]) than with LDP (67% [16/24]; p = 0.011). Postoperative complication rates did not differ significantly between the two groups.

conclusionsCompared with LDP, RDP was associated with significantly reduced intraoperative blood loss, a lower conversion rate to open surgery, and a higher success rate in splenic vessels preservation, suggesting the technical advantages of RDP.
