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

backgroundRecently, Olympus Corporation released new scopes (XZ1200/EZ1500). However, there have been few reports on this topic, although improvement in adenoma detection rate (ADR) by texture and color enhancement imaging (TXI) or computer-aided detection system (CAD) has been reported.

aimTo investigate the effects of the scope on the detection of adenomas and sessile serrated lesions (SSLs).

methodsThe subjects were patients who underwent pancolonic chromoendoscopy using the EVIS X1 video system center between May 2023 and October 2024. The patients were divided into the new (CF-XZ1200/CF-EZ1500) and 290 series (CF-HQ290Z/PCF-H290Z) groups. Propensity score matching was performed for age, sex, examination purpose, endoscopist, preparation, TXI use, and CAD use. The effects of the scope were analyzed in terms of the ADR, SSL detection rate (SDR), and mean number of adenomas per colonoscopy (APC).

resultsOf the 7014 patients enrolled, 2138 pairs were extracted by propensity score matching (mean age 55.4 years, 45.5% male). The new scopes group had a significantly higher ADR than the 290 series group [51.5%

conclusionIn conclusion, the new scope (CF-XZ1200/CF-EZ1500) enhanced the detection of adenomas and SSLs compared to the old ones (290 series).
