Anatomical versus nonanatomical resection of colorectal liver metastases: a meta-analysis.

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.
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
purposeThe purpose of the study was to compare anatomical resection (AR) versus nonanatomical resection (NAR) for colorectal liver metastases (CLM) with respect to perioperative and oncological outcomes.
methodsLiterature search was performed to identify comparative studies reporting outcomes for both AR and NAR for CLM. Pooled odds ratios (OR) and weighted mean differences (WMD with 95% confidence intervals (95% CI) were calculated using either the fixed effects model or random effects model.
resultsSeven nonrandomized controlled studies matched the selection criteria and reported on 1,662 subjects, of whom 989 underwent AR, and 673 underwent NAR for CLM. Compared with the perioperative results, NAR reduced the operation time (WMD, 0.39; 95% CI, 1.97-79.17) and blood transfusion requirement (OR, 2.98; 95% CI, 1.87-4.74), whereas postoperative morbidity and mortality were similar between the two groups. With respect to oncologic outcomes, there was no significant difference in surgical margins, overall survival and disease-free survival between the two groups.
conclusionsNAR is a safe procedure for CLM and does not compromise oncological outcomes. However, the findings have to be carefully interpreted due to the lower level of evidence.
