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: Limited longitudinal knowledge exists between dietary patterns (DPs) in Africans and the incidence of type 2 diabetes (T2D). Objective: We investigated the association between 3 prevalent DPs among Ghanaians and incident T2D across geographical contexts. Methods: One thousand three hundred and fifty-three participants from the prospective Research on Obesity and Diabetes in African Migrants study were followed up for a median duration of 6.7 (6.4, 6.9) y. Three previously established DPs from our baseline data (i.e., "mixed pattern," "animal pattern," and "roots and tubers pattern") were used, and T2D incidence was determined based on World Health Organization criteria. Poisson regression models were used to analyze the associations between terciles of these DPs and incident T2D at follow-up among the entire population, by geographical context, and by sex, accounting for important covariates. Results: The study revealed a significant association between the "animal DP" and incident T2D among the total population compared to the lower tercile of intake [incidence rate ratio (IRR) was 2.72; 95% confidence interval (CI): 1.18, 6.28 in the upper tercile and 3.33; 95% CI: 1.55, 7.17 in the middle tercile]. However, when disaggregated by study site (rural Ghana, urban Ghana, and Amsterdam), these associations did not reach statistical significance, likely due to reduced statistical power in the stratified analyses. There was significant interaction between animal DP and sex, with increased risks among females (IRR: 6.76; 95% CI: 1.36, 39.5). Also, a higher intake of root, tubers, and plantain DP tercile was associated with a lower risk of T2D, although not statistically significant. Conclusions: We observed a positive association between adherence to an animal DP and the incidence of T2D, particularly among females. Dietary modifications toward a lesser consumption of an animal-pattern diet may reduce risk of T2D at the population level.
