Pro-inflammatory dietary patterns and their association with cardiovascular disease and pancreatic cancer in a hospital population: a cross-sectional study.

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
Objective: To examine whether a concise, clinic-feasible Patient Inflammatory Diet Score (PIDS) relates to prevalent pancreatic cancer and cardiovascular disease (CVD) in a hospital population, and to explore associations with systemic inflammation. Methods: We conducted a cross-sectional study among 401 adults (≥40 years) attending cardiology, gastroenterology, or oncology services (2018-2022). A 10-12-min questionnaire captured sociodemographics, lifestyle, and habitual intake of pro- and anti-inflammatory food groups to derive the PIDS (quartiles). Pancreatic cancer and CVD were ascertained from de-identified electronic records; high-sensitivity C-reactive protein (hsCRP) indexed systemic inflammation. Robust Poisson models estimated prevalence ratios (PRs) across PIDS quartiles with prespecified adjustments and subgroup/sensitivity analyses. Results: Pancreatic cancer was present in 24 participants (6.0%); CVD in 111 (27.7%). Relative to Q1, fully adjusted PRs for pancreatic cancer were 0.81 (95% CI 0.32-2.06), 0.94 (0.39-2.27), and 1.09 (0.45-2.65) for Q2-Q4 (p-trend = 0.79); the per-SD estimate was 1.03 (0.81-1.31). PIDS showed no material association with prevalent CVD (Q4 vs. Q1, PR 1.08; 0.76-1.54; p-trend = 0.61). Correlation with hsCRP was weak ( Conclusion: In this pragmatic clinical setting, a brief, food-based inflammatory diet score did not discriminate cross-sectional differences in pancreatic-cancer prevalence or CVD, nor did it correlate meaningfully with hsCRP. These null findings bound plausible effect sizes and support the need for larger, prospective studies with richer dietary phenotyping and biomarker integration.
