Dietary and lifestyle insulinemic potentials, plasma metabolome, and risk of diverticulitis: a prospective cohort study.
Article in The American journal of clinical nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundDiet and lifestyle factors have been linked to developing diverticulitis. However, it remains largely unknown whether the associations are mediated by metabolic disturbance, such as hyperinsulinemia and corresponding metabolomic perturbations.
objectivesWe investigated associations of the insulinemic potential of diet, lifestyle (diet, physical activity, body weight), and metabolomic patterns with the risk of incident diverticulitis.
methodsWe conducted a prospective cohort study including participants in 3 nationwide cohorts of United States health professionals. The risk of incident diverticulitis was estimated according to quintiles of the empirical dietary index for hyperinsulinemia (EDIH) and empirical lifestyle index for hyperinsulinemia (ELIH). In a subset of participants with metabolomic measurements, we developed metabolomic dietary index for hyperinsulinemia (MDIH) and metabolomic lifestyle index for hyperinsulinemia (MLIH), metabolite profile scores correlating with EDIH and ELIH, respectively, and tested their associations with subsequent risk of diverticulitis. We also examined whether the associations of EDIH and ELIH with diverticulitis were mediated by the metabolite profile scores.
resultsAmong 184,508 participants [median age, 51 (interquartile range, 46-56) y], we documented 9123 incident diverticulitis cases over 3,419,945 person-years. Compared with those in the lowest quintile, participants with the most hyperinsulinemic diets and lifestyles (highest quintiles of EDIH and ELIH) had a hazard ratio for the risk of diverticulitis of 1.22 [95% confidence interval (CI): 1.13, 1.31] and 1.69 (95% CI: 1.57, 1.81), respectively. Similarly, the metabolite profile scores were significantly associated with the diverticulitis risk with odds ratio of 1.96 for MDIH (95% CI: 1.47, 2.60) and 1.93 for MLIH (95% CI: 1.48, 2.51) when comparing extreme quintiles. The explainable proportions of EDIH- and ELIH-related diverticulitis risk by MDIH and MLIH were 70% (95% CI: 6%, 99%) and 57% (95% CI: 23%, 86%), respectively (P < 0.0001 for both).
conclusionsParticipants with dietary and lifestyle patterns corresponding to higher insulinemic potential had an increased risk of diverticulitis, which might be mediated by metabolomic profiles.
