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

<p>Introduction: Non-ampullary duodenal epithelial tumors with a gastrointestinal mixed phenotype (mixed-type NADETs) have not been thoroughly analyzed. We aimed to elucidate the clinicopathological and endoscopic characteristics of mixed-type NADETs.

methodsA total of 229 NADETs from 218 patients collected from February 2010 to December 2023 were analyzed. Based on immunohistochemistry for MUC5AC, MUC6, MUC2, and CD10, the NADETs were classified into gastric phenotype (GP), gastric predominant mixed phenotype (GPP), intestinal predominant mixed phenotype (IPP), and intestinal phenotype (IP).

resultsAmong the 229 NADETs, there were 20, 22, 69, and 118 lesions classified as GP, GPP, IPP, and IP, respectively. Tumor location (first/second/third) was GP = 13/7/0, GPP = 12/8/2, IPP = 13/52/4, and IP = 16/94/8 (p < 0.01). Mean tumor sizes of GP, GPP, IPP, and IP were 14.7/18.5/10.9/10.3 mm (p < 0.01), respectively. The ratio of category 4/5 by Vienna classification was 50.0, 68.2, 13.0, and 2.5% (p < 0.01), respectively. In the comparisons between GP vs. GPP and IP vs. IPP, white opaque substance was significantly less frequently observed in GP than in GPP (p < 0.05), the ratio of category 4/5 was significantly higher in IPP than in IP (p < 0.01), but no significant differences were observed in tumor location, coloration, macroscopic type, and endoscopic findings including magnifying endoscopy with narrow-band imaging.

conclusionMixed-type NADETs (GPP and IPP) exhibited similar endoscopic and clinicopathological characteristics to their predominant phenotypes, and may have a higher malignant potential than the pure phenotypes. </p>.
