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

purposeTransanal total mesorectal excision (TaTME) has the potential advantages for patients with low rectal cancer. The objective of this meta-analysis was to identify the pathologic outcomes between the TaTME and laparoscopic total mesorectal excision (LaTME) in rectal cancer.

methodsThe literature searches were conducted in PubMed, Cochrane Library, and EMBASE with English language restriction. The primary endpoint was circumferential margin (CRM), and the secondary endpoints were distal resection margin (DRM), mesorectal excision quality, and harvested lymph nodes.

resultsOur research identified 1090 articles, and 26 studies met the inclusion criteria for the meta-analysis. The positive CRM was lower in the TaTME than the LaTME (OR = 0.72; 95% CI = 0.53, 0.98; P = 0.04). There was no significant difference in the positive CRM between the TaTME and LaTME published after 2016 (OR = 0.80; 95% CI = 0.57, 1.12; P = 0.19), prospective study (OR = 2.70; 95% CI = 0.51, 14.24; P = 0.24), respective study (OR = 0.76; 95% CI = 0.55, 1.04; P = 0.09), BMI > 26 (OR = 1.00; 95% CI = 0.63, 1.58; P = 0.98), or sample size > 100 (OR = 0.84; 95% CI = 0.57, 1.23; P = 0.38). In addition, there was no significant difference observed between the TaTME and LaTME in terms of DRM, mesorectum incompleteness, and harvested lymph nodes.

conclusionsThe TaTME is associated with lower positive CRM compared to the LaTME and similar pathologic outcomes including DRM, harvested lymph node, and mesorectal excision quality.
