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

backgroundMinor liver resections of posterosuperior segments (1, 4A, 7, 8) are challenging to perform laparoscopically and are mainly performed using an open approach. We determined the feasibility of robotic resections of posterosuperior segments and compared short-term outcomes with the open approach.

methodsData on open and robotic minor (≤ 3 segments) liver resections including the posterosuperior segments, performed between 2009 and 2016, were collected retrospectively from four hospitals. Robotic and open liver resections were compared, before and after propensity score matching.

resultsIn total, 51 robotic and 145 open resections were included. After matching, 31 robotic resections were compared with 31 open resections. Median hospital stay was 4 days (interquartile range [IQR] 3-7) for the robotic group, versus 8 days (IQR 6-10) for the open group (p < 0.001). Median operative time was 222 min (IQR 164-505) for robotic cases versus 231 min (IQR 190-301) for open cases (p = 0.668). Median estimated blood loss was 200 mL (IQR 100-400) versus 300 mL (IQR 125-750), respectively (p = 0.212). In the robotic group, one patient (3%) had a major complication, versus three patients (10%) in the open group (p = 0.612). Readmissions were similar-10% in the robotic group versus 6% in the open group (p > 0.99). There was no mortality in either group.

conclusionMinor robotic liver resections of the posterosuperior segments are safe and feasible and display a shorter length of stay than open resections in selected patients at expert centers.
