Role of dietary patterns and inter-meal intervals in hypopharyngeal cancer: A case-control study from Assam, India.

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
Background and objectives Despite a high incidence of hypopharyngeal cancer in northeast India, the role of dietary patterns and meal timing remains poorly understood. This study examined the association between inter-meal intervals, dietary patterns, and the risk of hypopharyngeal cancer in northeastern India. Methods A hospital-based case-control study was conducted at a tertiary cancer centre in northeastern India, enrolling 300 histologically confirmed cases with hypopharyngeal cancer and 300 frequency-matched controls between May 2023 and August 2024. Dietary intake and inter-meal intervals were assessed using a semi-quantitative food frequency questionnaire. Multivariable logistic regression calculated odds ratios and 95% confidence intervals, adjusting for demographics, socioeconomic status, alcohol consumption, smoking, and tobacco use, including areca nut consumption. Results Prolonged inter-meal intervals (≥5 h) conferred a nearly three-fold increased risk of hypopharyngeal cancer compared to intervals <4 h [adjusted odds ratio (OR) 2.69, 95% confidence interval (CI): 1.56-4.69]. Strong protective effects emerged for citrus fruits (highest tertile OR 0.13, 95% CI: 0.05-0.32) and leafy green vegetables (highest tertile OR 0.21, 95% CI: 0.09-0.49). Coffee consumption was inversely associated with the risk of hypopharyngeal cancer (OR 0.54, 95% CI: 0.30-0.94), while higher milk intake increased the risk of hypopharyngeal cancer (OR 2.06, 95% CI: 1.22-3.52). Interpretation and conclusions We provide epidemiological evidence linking prolonged inter-meal intervals to the risk of hypopharyngeal carcinoma in an Indian population. Meal timing patterns may be as important as dietary composition for cancer prevention, with implications for public health interventions in high-risk populations.
