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.
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
backgroundAlthough cancer antigen 19-9 (CA 19-9) is the only FDA-approved biomarker for pancreatic ductal adenocarcinoma (PDAC), its diagnostic effectiveness is limited, as it may not be elevated in 15-25% of patients. This study aims to explore novel plasma proteins associated with PDAC as potential biomarkers for early diagnosis and clinical surveillance.
methodsNovel plasma protein biomarkers potentially causally associated with PDAC were identified using Mendelian randomization (MR). These biomarkers were validated in a multicenter study encompassing 230 tissue and 1,011 plasma samples to establish a diagnostic model for PDAC. Furthermore, their pre- and post-operative levels were compared to evaluate their potential as clinical surveillance biomarkers.
resultsGenetically predicted expression of seven proteins potentially causally associated with an increased risk of PDAC. In a multicenter, large-scale study, Keratin 5 (KRT5) and Versican (VCAN) were identified as promising biomarkers for PDAC, with an area under the curve (AUC) of 0.90, and a combined panel including CA 19-9 achieved an AUC of 0.95. Additionally, plasma KRT5 and VCAN demonstrated superior diagnostic performance for early-stage PDAC with CA 19-9 levels below 37 U/mL (Stage I, AUC 0.85; Stage II, AUC 0.85). The specificity of plasma KRT5 and VCAN for PDAC was further validated by comparing their expression levels across various digestive cancers. Moreover, a significant decrease in plasma KRT5 and VCAN levels was observed post-surgery (P < 0.05), supporting their potential as biomarkers for clinical surveillance of PDAC.
conclusionsPlasma KRT5 and VCAN proteins may serve as promising valuable biomarkers for the early diagnosis and clinical surveillance of PDAC.
