The linear association between pulse pressure and diabetic retinopathy: a cross-sectional study.
Article in Frontiers in cardiovascular medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: This study aimed to evaluate the relationship between pulse pressure (PP) and the prevalence of diabetic retinopathy (DR) in individuals diagnosed with type 2 diabetes mellitus. Methods: This research is a secondary analysis of a cross-sectional study conducted between April 2002 and November 2004, which included 2,001 adults with diabetes mellitus (859 men and 1,142 women, mean age 64.1 ± 11.3 years) recruited from outpatient clinics in southern Taiwan. Comprehensive demographic and clinical data were collected, defining pulse pressure as the difference between systolic blood pressure (SBP) and diastolic blood pressure (DBP) measured in mmHg. The association between PP and DR was assessed using multivariable logistic regression, adjusting for potential confounders, and a generalized additive model (GAM) was utilized to explore non-linear relationships. Results: Elevated PP levels were consistently associated with higher odds of prevalent DR across progressively adjusted models. When PP was modeled per 10-mmHg increment, the association remained significant in Model 1 (OR 1.16; 95% CI 1.09-1.23; Conclusions: This study indicates higher PP was associated with higher odds of prevalent DR in individuals with type 2 diabetes.
