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

backgroundNational dietary guidelines contribute to primary prevention of a wide range of diseases. Yet, the importance of adhering to the Danish dietary guidelines for colorectal cancer prevention is unclear.

methodsWe used the Danish Diet, Cancer and Health cohort (n = 55,744) to investigate adherence to the Danish dietary guidelines and the risk of colorectal cancer. Cox proportional hazard models were used to estimate hazard ratios (HRs) for colorectal cancer and subtypes across the Danish Dietary Guidelines Index score (ranging 0-6 points, 6 being the greatest adherence). Effect modification by BMI was explored on multiplicative and additive scales.

resultsDuring a median follow-up of 18.9 years, 1030 men and 849 women developed colorectal cancer. Higher index scores were associated with a lower risk of colorectal cancer (HR 0.66; 95% confidence interval (CI) 0.53, 0.84, highest (≥5) versus lowest index score (<3 points) group). Similar inverse associations were observed between index scores and colon cancer. The risk difference was -0.8% (95% CI: -1.6, -0.1) among the overweight/obese group and 0.1% (95% CI: -0.7, 1.0) in the normal weight group for high compared to low adherence.

conclusionAdherence to the Danish Dietary Guidelines was associated with a lower risk of colorectal cancer, particularly among people with overweight/obesity.
