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

BACKGROUND AND

aimsEndoscopic full-thickness resection (eFTR) is a field of increasing interest that offers a minimally invasive resection modality for lesions that are not amenable for resection by conventional methods. Full-thickness resection device (FTRD) is a new device that was developed for a single-step eFTR using an over-the scope-clip. In this meta-analysis, we aim to assess the efficacy and safety of FTRD for eFTR of colorectal lesions.

methodsA Comprehensive literature review of different databases to identify studies reporting FTRD with outcomes of interest was performed. Studies with <10 cases were excluded. Rates of histologic complete resection (R0), technical success, and complications were extracted. Efficacy was assessed by using the technical and the R0 rates whereas safety was assessed by using the complications rates. Weighted pooled rates (WPRs) and the 95% confidence interval (CI) were calculated depending on the heterogeneity (I2 statistics).

resultsNine studies including 551 patients with 555 lesions were included in this study. The WPR for overall R0 was 82.4% (95% CI: 79.0%-85.5%),with moderate heterogeneity (I2=34.8%). The WPR rate for technical success was 89.25% (95% CI: 86.4%-91.7%), with low heterogeneity (I2=23.7%). The WPR for total complications rate was 10.2% (7.8, 12.8%) with no heterogeneity. The pooled rate for minor bleeding, major bleeding, postpolypectomy syndrome, and perforation were 3.2%, 0.97%, 2.2%, and 1.2%, respectively. Of 44 periappendicular lesions, the pooled rate for acute appendicitis was 19.7%.

conclusionsFTRD seems to be effective and safe for eFTR of difficult colorectal lesions. Large prospective studies comparing FTRD with conventional resection techniques are warranted.
