Clinical Characteristics and Outcomes of Hospitalized Patients With COVID-19 and Type 2 Diabetes in Vietnam: A Retrospective Study.
Article in Cureus, 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 describe the clinical characteristics and outcomes of hospitalized patients with COVID-19 and diabetes mellitus in Vietnam. MATERIALS AND
methodsA retrospective descriptive study was carried out from June 2021 to September 2022 at the Hospital for Tropical Diseases, a tertiary care center in Ho Chi Minh City, Vietnam.
resultsThe study included 154 patients with COVID-19 and diabetes mellitus. The mean age was 65 years, and women accounted for 64.3% of the study population. Prior COVID-19 vaccination was documented in 39.6% of patients. The mean duration of illness before hospitalization was 5 ± 3 days (range, one to 15 days). At admission, 71.8% of patients required oxygen support. The most common clinical manifestations were cough, dyspnea, and fever, while chest pain and diarrhea were less frequently observed. Common in-hospital complications included cytokine storm, acute respiratory distress syndrome (ARDS), sepsis, septic shock, ventilator-associated pneumonia, and urinary tract infection. Less frequent complications were ketoacidosis, hyperosmolar hyperglycemic state, and myocardial infarction. Most patients had a previous diagnosis of diabetes, whereas 14.3% were newly diagnosed during hospitalization on the basis of glycated hemoglobin (HbA1c). The mean length of hospital stay was 16 ± 10 days (range, two to 71 days), and the mortality rate was 20%.
conclusionHospitalized patients with COVID-19 and diabetes mellitus had a substantial clinical burden, reflected by frequent oxygen requirements, severe complications, prolonged hospitalization, and considerable mortality. These findings underscore the need for close monitoring and careful metabolic management in this high-risk population.
