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 aimed to investigate the differences in surgical difficulty between laparoscopic partial liver resections of segments 7 and 8.

methodsWe analyzed 173 patients who underwent partial liver resections of segments 7 or 8 between 2010 and 2022 at two institutions. We investigated differences in the surgical outcomes of each procedure using propensity score matching. We compared these outcomes with those of open partial liver resections for segments 7 and 8 to determine whether the differences were unique to the laparoscopic approach.

resultsThirty and 54 patients underwent laparoscopic partial liver resections of segments 7 and 8. In the matched cohort (22 in each group), the operation time was significantly longer (377 vs. 278 min, P = 0.020) and the proportion of postoperative complications significantly higher in segment 7 (27% vs. 0%, P = 0.008). Forty-one and 48 patients underwent open partial liver resections of segments 7 and 8, respectively. There were no significant differences in the surgical outcomes between the segments in the matched cohort (20 in each group).

conclusionsLaparoscopic partial liver resections of segment 7 may be more challenging than that of segment 8. This difference in difficulty was not observed in open partial liver resections.
