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/

aimClaudin 18.2 (CLDN18.2) has emerged as a highly selective biomarker and its abnormal expression has been reported in various primary malignant tumors. Recently, CLDN18.2 has gained attention as both a prognostic biomarker and a potential therapeutic target in gastric and gastroesophageal junction cancer. The purpose of this study was to investigate CLDN18.2 expression in a large cohort of 168 prostate cancer (PC) tissues, assess its correlation with clinicopathological factors, and evaluate its potential as a therapeutic target for anti-CLDN18.2 therapy. MATERIALS AND

methodsImmunohistochemical staining was conducted using an approved diagnostic CLDN18.2 immunohistochemistry protocol (Ventana, 43-14A clone). Interpretation was carried out following the general rules for staining evaluation.

resultsNon-neoplastic gastric mucosa, used as a positive control for CLDN18.2 immunostaining, exhibited strong membranous staining. In contrast, no CLDN18.2 expression was detected in normal ductal and acinar cells of prostate tissue, nor in any of the 168 variable PC tissues.

conclusionCLDN18.2 is not expressed in normal prostate tissue or PC, suggesting that it is unlikely to serve as a prognostic marker or a potential target for immunotherapy in PC.
