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 study aims: First surveillance colonoscopy (SC1) following piecemeal endoscopic mucosal resection (pEMR) is recommended at 3 to 6 months. We aimed to investigate whether delayed SC1 is associated with increased risk of recurrence. Patients and methods: This was a retrospective analysis of a prospective cohort of patients undergoing pEMR for large non-pedunculated colorectal polyps (LNPCPs). Patients were categorized into standard SC1 (3-6 months) and delayed SC1 (> 6 months) groups. The primary endpoint was recurrence at SC1. Secondary outcomes included recurrence at second surveillance colonoscopy (SC2) and features of lesion recurrence. Subgroup analyses of very delayed SC1 and high-risk lesions were performed. Recurrence rates were also evaluated with propensity score matching (PSM). Results: We analyzed 577 lesions (standard: 407, delayed: 170) with a median polyp size of 30 mm (interquatile range [IQR] 25-40). Median time to SC1 was 5 months (IQR 5-6) in the standard versus 9 months (IQR 7-13) in the delayed group ( Conclusions: Delayed SC1 is not associated with increased recurrence rates. Complete resection can be anticipated for most lesions and SC1 at 1-year post resection may be sufficient.
