Potato Consumption and Risk of Type 2 Diabetes Mellitus: A Harmonized Analysis of 7 Prospective Cohorts.
Article in The Journal of nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundData on the relation of potato consumption with risk of type 2 diabetes (T2D) are limited and inconsistent. It is unclear whether the plant-based diet index (PDI), which is a novel and comprehensive tool to assess overall dietary pattern, modifies the association of potato intake with T2D.
objectivesWe examined the association of total, combined baked, boiled, and mashed potatoes and fried potatoes with risk of T2D and test the interaction between PDI score and potato consumption on T2D risk.
methodsWe conducted a de novo, harmonized, individual-level data from 7 United States cohorts (N = 105,531). Cox regression was used to estimate hazard ratios (HRs) separately in each cohort adjusting for anthropometric, demographic, and lifestyle factors and cohort-specific results were pooled using an inverse-variance weighted method.
resultsMean age ranged from 25 to 72 y, 65% women, and mean consumption of total potatoes ranged from 1.9 to 4.3 times per week. In the primary analysis, total potato intake was not associated with T2D risk: multivariable adjusted HR of 1.01 (95% confidence interval [CI]: 0.95, 1.08) for consumption of 1-2 servings/wk; 1.01 (95% CI: 0.93, 1.10) for >2-3 servings/wk; 1.05 (95% CI: 0.99, 1.12) for >3 to <5 servings/wk; and 1.07 (95% CI: 0.99, 1.16) for 5+ servings/wk compared with no potato intake. In secondary analyses, consumption of combined baked, boiled, and mashed potatoes was not associated with T2D risk, whereas fried potato consumption was positively associated with T2D risk: HR were 1 (ref), 1.07 (95% CI: 1.02, 1.12), and 1.12 (95% CI: 1.03, 1.22) for intake frequency of 0/wk, >0 to 1/wk, and >1/wk, respectively (P-trend = 0.04). There was no significant interaction between PDI score and potato consumption on T2D risk.
conclusionsAlthough consumption of total potato is not associated with T2D risk, a modest elevated risk of T2D is observed with fried potato consumption.
