Lifestyle factors, genetic susceptibility and risk of incident diverticulitis: an integrated analysis of four prospective cohort studies and electronic health records-linked biobank.

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
backgroundBoth lifestyle factors and genetic predisposition contribute to the development of diverticulitis.
objectiveTo examine whether lifestyle modification can reduce the genetic risk of diverticulitis.
designWe derived an overall healthy lifestyle score for diverticulitis based on smoking, body mass index (BMI), physical activity, fibre and red meat among 179 564 participants in three prospective cohorts-the Nurses' Health Study (NHS), NHSII and the Health Professionals Follow-Up Study. The association between the healthy lifestyle score and incident diverticulitis was confirmed among 30 750 participants in the Southern Community Cohort Study (SCCS). We assessed genetic risk using a polygenic risk score among 36 077 individuals with genotype data available. We further validated our findings in the Mass General Brigham Biobank (MGBB).
resultsA healthy lifestyle score was associated with a decreased risk of diverticulitis. Compared with a score of 0, the multivariable-adjusted HR for a score of 5 was 0.50 (95% CI, 0.44 to 0.57; p trend<0.0001). This association was consistent across the SCCS in both non-Hispanic black and white populations. Each unit increase in the healthy lifestyle score was associated with a reduced diverticulitis risk similarly across genetic risk categories, with HRs of 0.89 (95% CI, 0.83 to 0.95) for low, 0.86 (0.81 to 0.92) for mid and 0.87 (0.83 to 0.91) for high genetic risk. In the MGBB cohort, a higher BMI was associated with an increased diverticulitis risk across genetic risk categories.
conclusionMaintaining a healthy lifestyle was associated with a reduced risk of developing diverticulitis, regardless of population differences and genetic susceptibilities.
