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

objectiveTo evaluate the effect of a novel-designed colonoscopic distal attachment on the diagnosis of polyps during colonoscopy.

methodAll consecutive patients who underwent routine colonoscopic examinations at Tongji Hospital endoscopy centers in China were enrolled. Participants were randomly assigned in a 1:1 ratio to the auxiliary devices colonoscopy (Experimental Group) or standard colonoscopy groups (Control Group). Adenoma detection rate (ADR), polyp detection rate (PDR), inspection time, duration of treatment and adverse events were recorded.

resultA total of 264 patients were randomized into the experimental group (EG, n = 132) and the control group (CG, n = 132). The PDR in the EG was significantly higher than in the CG (p = 0.013), while no significant difference was found in the ADR between the two groups (p = 0.078). Insertion and withdrawal times for colonoscopy were showed no statistically significant difference (p = 0.096 and p = 0.868, respectively). Analysis of polyp detection conditions revealed that the EG had a higher number of polyps detected(p = 0.013), and detected more polyps ≤ 5 mm (p = 0.018), and there was no significant difference in the location distribution of detected polyps between the two groups (p = 0.950). Treatment times were showed statistically significant differences, with the EG having shorter treatment times (p = 0.004).

conclusionThe use of auxiliary devices in colonoscopy significantly improves the PDR, espicialy no-adnoma or smaller polyp, and reduces treatment times compared to standard colonoscopy.
