Distribution of cholecystokinin-B receptor genotype between patients with pancreatic cancer and controls and its impact on survival.
Article in Pancreas, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
objectiveCholecystokinin (CCK) and gastrin stimulate growth of pancreatic cancer through the CCK-B receptor (CCK-BR). A splice variant of the CCK-BR that results from a single nucleotide polymorphism (SNP) has been identified. Because the splice variant receptor has an extended third intracellular loop, an area involved in cell signaling and growth, we hypothesized that this genetic variant could contribute to the poor prognosis and short survival of this malignancy.
methodsDNA from 931 patients with pancreatic cancer was evaluated for the SNP (C > A; rs1800843) in the CCK-BR gene. For statistical analysis, the Fisher exact test was used to compare the genotype and allele frequency between the cancer cohort and normal controls and the dependence of genotype on factors, such as stage of disease and age, was analyzed using Cox proportional hazards models.
resultsCompared to the normal cohort, the frequency of the A-allele in pancreatic cancer subjects was increased (P = 0.01123; odds ratio, 2.283). Even after adjustment for stage of disease, survival of subjects with the minor allele was significantly shorter than those with the wild-genotype (hazard ratio, 1.83; P = 3.11 × 10(-11)).
conclusionsThe CCK-BR SNP predicts survival and should be studied as a candidate genetic biomarker for those at risk of pancreatic cancer.
