Ketoacidosis at diagnosis of diabetes mellitus type 1: impact of the COVID-19 pandemic.
Observational study in Revista da Associacao Medica Brasileira (1992), 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
objectiveThe objective of this study was to identify the frequency and severity of diabetic ketoacidosis in the diagnosis of type 1 diabetes mellitus in the pre-, during-, and post-COVID-19 pandemic periods at a state-reference pediatric center.
methodsObservational, cross-sectional period study, including medical records of patients diagnosed with type 1 diabetes mellitus from 2018 to 2024. The association between the diagnosis period and the presence of diabetic ketoacidosis was assessed using odds ratios with 95%CIs. The association between the diagnosis period and the need for intensive care unit admission, symptom duration, and previous incorrect diagnoses was assessed using Fisher's exact test. Temporal trends in diabetic ketoacidosis severity were assessed using the Cochran-Armitage trend test. p<0.05 were considered significant.
resultsOf the 184 type 1 diabetes mellitus cases, 55.4% presented with diabetic ketoacidosis at diagnosis. Patients diagnosed during the pandemic had a higher chance of developing diabetic ketoacidosis compared to the pre-pandemic period (OR 3.17; 95%CI 1.52-6.64; p=0.002) and the post-pandemic period (OR 2.90; 95%CI 1.37-6.16; p=0.005). There was no significant association between the diagnosis period and the occurrence of previous incorrect diagnoses, between the diagnosis period and the time of symptom progression, and intensive care unit admission. Regarding the severity of diabetic ketoacidosis, no significant temporal trend was identified (p>0.05).
conclusionAn association was observed between the pandemic period and the occurrence of diabetic ketoacidosis, without inference of causality. There are no significant differences in the proportion of severe diabetic ketoacidosis during the pandemic period.
