Gene Variants That Affect Levels of Circulating Tumor Markers Increase Identification of Patients With Pancreatic Cancer.
Article in Clinical gastroenterology and hepatology : the official clinical practice journal of the American Gastroenterological Association, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
BACKGROUND &
aimsLevels of carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and cancer antigen 125 (CA-125) in blood are used as markers to determine the response of patients with cancer to therapy, but are not used to identify patients with pancreatic cancer.
methodsWe obtained blood samples from 504 patients undergoing pancreatic surveillance from 2002 through 2018 who did not develop pancreatic cancer and measured levels of the tumor markers CA19-9, CEA, CA-125, and thrombospondin-2. Single-nucleotide polymorphisms (SNPs) in FUT3, FUT2, ABO, and GAL3ST2 that have been associated with levels of tumor markers were used to establish SNP-defined ranges for each tumor marker. We also tested the association between additional SNPs (in FUT6, MUC16, B3GNT3, FAM3B, and THBS2) with levels of tumor markers. To calculate the diagnostic specificity of each SNP-defined range, we assigned the patients under surveillance into training and validation sets. After determining the SNP-defined ranges, we determined the sensitivity of SNP-adjusted tests for the tumor markers, measuring levels in blood samples from 245 patients who underwent resection for pancreatic ductal adenocarcinoma (PDAC) from 2010 through 2017.
resultsA level of CA19-9 that identified patients with PDAC with 99% specificity had 52.7% sensitivity. When we set the cut-off levels of CA19-9 based on each SNP, the test for CA19-9 identified patients with PDAC with 60.8% sensitivity and 98.8% specificity. Among patients with FUT3 alleles that encode a functional protein, levels of CA19-9 greater than the SNP-determined cut-off values identified 66.4% of patients with PDAC, with 99.3% specificity. In the validation set, levels of CEA varied among patients with vs without SNP in FUT2, by blood group, and among smokers vs nonsmokers; levels of CA-125 varied among patients with vs without the SNP in GAL3ST2. The use of the SNPs to define the ranges of CEA and CA-125 did not significantly increase the diagnostic accuracy of the assays for these proteins. Combining data on levels of CA19-9 and CEA, CA19-9 and CA-125, or CA19-9 and thrombospondin-2 increased the sensitivity of detection of PDAC, but slightly reduced specificity.
conclusionsIncluding information on SNPs associated with levels of CA19-9, CEA, and CA-125 can improve the diagnostic accuracy of assays for these tumor markers in the identification of patients with PDAC. Clinicaltrials.gov no: NCT02000089.
