Prediction of acute metabolic complications in hospitalized elderly patients with type 2 diabetes using admission HbA1c and hypertension: a retrospective cohort study.
Article in American journal of translational research, 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
objectiveTo identify admission-based predictive indicators for in-hospital acute metabolic complications in elderly patients with type 2 diabetes mellitus (T2DM), and to develop and internally validate a simple predictive model for early risk stratification.
methodsA total of 203 elderly inpatients with T2DM were included in this retrospective cohort study. According to the occurrence of acute metabolic complications during hospitalization, patients were divided into a complication group (n = 40) and a non-complication group (n = 163). All candidate predictive indicators were collected from admission medical records and laboratory test results obtained within 24 to 48 hours after admission. Univariate and multivariate logistic regression analyses were performed to screen for independent predictive factors. The model's discriminatory power was evaluated using the area under the receiver operating characteristic curve (AUC), and 1000 bootstrap resamplings were adopted for internal validation.
resultsThe complication group had significantly higher admission HbA1c levels than the non-complication group (P<0.001), as well as a higher prevalence of hypertension (P = 0.002). Multivariate regression analysis verified that HbA1c (OR = 1.761, 95% CI: 1.44-2.15, P<0.001) and hypertension (OR = 3.904, 95% CI: 1.60-9.53, P = 0.003) were independent risk factors for in-hospital acute metabolic complications. The predictive model based on these two indicators exhibited good discriminatory performance, with an original AUC of 0.836. After bootstrap internal validation, the optimism-corrected AUC was 0.726, indicating acceptable stability of the model.
conclusionElevated admission HbA1c and comorbid hypertension are independent predictive factors for in-hospital acute metabolic complications in elderly T2DM patients. This novel simple model has favorable predictive efficacy and stability, and it can serve as a feasible clinical tool for early risk stratification in elderly T2DM inpatients.
