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: Missed high-grade dysplasia (HGD) or adenocarcinoma in Barrett's esophagus (BE) may have serious consequences, although the attributes of post-endoscopy Barrett's neoplasia (PEBN) remain unexplored. We analyzed the characteristics of Barrett's neoplasia (BN) eluding detection during screening endoscopy. Methods: We retrospectively reviewed endoscopic images of BN, including HGD and adenocarcinoma, diagnosed at six centers in Nagano prefecture. Eligible patients had index endoscopic images obtained 7 to 36 months before BN diagnosis. Causes of PEBN were classified as perceptual error, in which BN was missed despite images taken where it was eventually diagnosed, or exposure error, whereby no images were obtained in the area of BN development. Results: Among the 91 patients with BN, 31 were judged as having PEBN. The majority of PEBN cases were attributed to perceptual error (22 patients, 71%). Lesions within long-segment BE (LSBE) were significantly more likely to be overlooked due to exposure error (67% vs. 18%, Conclusions: PEBN occurring in LSBE was mostly overlooked because of inadequate observation, whereas PEBN at the 0 to 3 o'clock position in SSBE was frequently misdiagnosed as esophagitis. Bearing these results in mind may improve quality of endoscopic screening and reduce incidence of PEBN.
