Patterns of complication burden in people with diabetes: a latent class analysis approach.
Article in Acta diabetologica, 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
aimsTo identify patterns of complication burden among individuals with diabetes mellitus based on sociodemographic, behavioral, and clinical characteristics, and to examine their co-occurrence with diabetes-related comorbidities.
methodsThis cross-sectional study was conducted during a diabetes health campaign in a municipality in southern Bahia, Brazil, involving 1,542 patients. Data were obtained through a standardized questionnaire and ophthalmological examinations. Latent class analysis was applied to identify subgroups with similar clinical characteristics. Models with two to four classes were estimated, with the two-class model presenting the most parsimonious and interpretable solution according to BIC. Associations between classes and comorbidities were estimated using Poisson regression with robust variance, adjusted for age and sex.
resultsTwo classes were identified. Class 1 (86.6%) showed lower complication burden, with preserved vascular and sensory function. Class 2 (13.4%) was characterized by a higher frequency of ulceration, amputation, absent peripheral pulses, and impaired protective sensation. Individuals in Class 2 presented higher prevalence of cardiovascular disease (PR = 1.47), myocardial infarction (PR = 1.64), neurological disease (PR = 1.67), and retinopathy (PR = 1.63).
conclusionThe identified classes primarily reflect differences in peripheral complication burden, with higher co-occurrence of vascular and microvascular conditions in the more affected group. These findings describe patterns of complication clustering within a screening population and may support population-level strategies for identifying individuals with greater healthcare needs.
