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

backgroundPreoperative interventions have increased the resectability of colorectal cancer (CRC) liver metastases. This retrospective study compares outcomes after liver resection for bilobar CRC metastases between patients who underwent parenchyma-sparing hepatectomy (PSH), i.e., segmentectomies and smaller resections on both lobes, and those treated with non-PSH, i.e., hemihepatectomy plus any resection on the other lobe.

methodsA cohort of 119 patients who underwent liver resection for bilobar CRC metastases were included. Perioperative course and long-term survival were compared between 59 patients who underwent PSH and 60 patients who underwent non-PSH. Statistical analyses were done using Pearson's chi-square test, Fisher's exact test and the Mann-Whitney

resultsThe median number of liver metastases was 2 in patients treated with PSH and 3 in those treated with non-PSH (P<0.01). Postoperative mortality, severe complications and radicality did not differ significantly between groups. Median intraoperative bleeding was 250 mL for PSH and 600 mL for non-PSH (P<0.001). Median operation time and hospital stay were significantly shorter for PSH. Overall survival was comparable between groups, also after adjustment for covariates.

conclusionsThere were no significant differences in outcome, except for differences in bleeding, operation time and postoperative stay, favoring PSH. Furthermore, minimizing resection did not influence radicality. Hence, this study supports the use of PSH for bilobar CRC liver metastases when possible.
