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: Several guidelines recommend discontinuation of routine surveillance colonoscopy after age 75 years. Because Japan has one of the longest life expectancies, we considered ceasing at age 80 years. We compared patients aged 75 to 79 years with those aged 70 to 74 years, regarding adenoma detection rate (ADR), mean number of adenomas per colonoscopy, and adverse events. Patients and methods: This propensity score-matching (PSM) study included patients aged 70 to 79 years with a performance status of 0 to 1 who underwent colonoscopies at Toyoshima Endoscopy Clinic between 2017 and 2024. Patients aged 75 to 79 years were matched with those aged 70 to 74 years for baseline characteristics using the propensity score. ADR, mean number of adenomas per colonoscopy, frequency of respiratory depression, hypotension, and delayed post-polypectomy bleeding were compared between the two groups. Results: During the study period, 3415 patients were included. The ADR in patients aged 75 to 79 years was higher than that in patients aged 70 to 74 years (66.5% vs 62.2%, Conclusions: Colonoscopies for patients aged 75 to 79 are safe and effective in Japan.
