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

backgroundMany epidemiologic studies have examined the association between C-reactive protein (CRP) and risk of cancer with inconsistent results.

methodsWe conducted two nested, case-control studies in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC) and Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) to test whether prediagnostic circulating CRP concentrations were associated with pancreatic adenocarcinoma. Between 1985 and 2004, 311 cases occurred in ATBC and between 1994 and 2006, 182 cases occurred in PLCO. Controls (n = 510 in ATBC, n = 374 in PLCO) were alive at the time the case was diagnosed and were matched by age, date of blood draw, sex, and race. We used conditional logistic regression adjusted for smoking to calculate OR and 95% CI for pancreatic cancer.

resultsCRP concentrations (ng/mL) tended to be inversely or not associated with pancreatic cancer risk in ATBC, PLCO, and combined analyses [per standardized quintile increase in CRP, continuous OR = 0.94 (95% CI, 0.89-0.99), OR = 0.99 (95% CI, 0.95-1.04), OR = 0.98 (95% CI, 0.95-1.01), respectively]. In combined analyses, we observed a significant interaction (P(interaction) = 0.02) such that inverse associations were suggestive in younger (OR = 0.95; 95% CI, 0.90-1.01), but not older, participants.

conclusionOur results do not support the hypothesis that higher CRP concentrations are associated with incident pancreatic cancer. IMPACT: Our results highlight the importance of investigating more specific biomarkers for inflammation that may reflect the biological mechanisms underlying pancreatic cancer in prospective cohort studies.
