Association between dietary oxidative balance scores and myocardial infarction in diabetic patients: insights from NHANES 1999-2018.

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
backgroundMyocardial infarction (MI) poses a serious health threat to diabetic patients, who are particularly vulnerable due to heightened oxidative stress. The dietary oxidative balance score (DOBS) quantifies the overall oxidative profile of the diet and may reflect diet-related cardiovascular risk.
objectiveThis study aimed to evaluate the association between DOBS and the risk of MI among diabetic individuals using a nationally representative U.S. POPULATION:
methodsWe analyzed data from 5,002 diabetic participants in the NHANES 1999-2018 cycles. DOBS was calculated based on 16 pro- and antioxidant nutrients using two 24-hour dietary recalls. Logistic regression models and 1:1 propensity score matching (PSM) were employed to assess the association between DOBS and self-reported history of MI, adjusting for demographic, clinical, and lifestyle covariates. Restricted cubic spline (RCS) models were used to evaluate potential nonlinear relationships.
resultsA one-point increase in DOBS was associated with a 3% lower odds of MI in both unadjusted and fully adjusted models (adjusted OR = 0.97, 95% CI: 0.95-0.99). Participants in the highest DOBS tertile had a 38% lower odds of MI compared to the lowest tertile (OR = 0.62, 95% CI: 0.43-0.87), and this association remained consistent in the matched cohort (OR = 0.72, 95% CI: 0.48-0.88). While formal tests for nonlinearity were not significant, RCS curves suggested a threshold effect with diminishing benefits at higher DOBS levels. Subgroup and sensitivity analyses confirmed the robustness of the findings.
conclusionHigher DOBS is associated with a lower likelihood of MI among diabetic patients. These findings highlight the potential value of antioxidant-rich dietary patterns in cardiovascular risk assessment. However, given geographic and cultural variability in diet, further validation is needed in diverse populations and prospective study settings.
