New-Onset Type 1 and Type 2 Diabetes Among Korean Youths During the COVID-19 Pandemic.
Article in JAMA pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Importance: Whether COVID-19 contributes to youth-onset diabetes is controversial, and research in Asia is lacking. Objective: To explore the incidence and severity of diabetes among youths during the COVID-19 pandemic in South Korea. Design, Setting, and Participants: This cohort study used claims data for January 1, 2017, through February 28, 2022, from the National Health Insurance Service database in South Korea. The incidence of type 1 diabetes (T1D) and type 2 diabetes (T2D) in patients younger than 20 years during the pandemic was analyzed and compared with that during the prepandemic period. The study included incident cases of T1D identified by at least 2 diagnosis codes with at least 2 insulin prescriptions within 1 year and T2D identified by at least 2 diagnosis codes with at least 2 prescriptions of diabetes medication within 1 year. Analyses were performed between January 29 and September 2, 2024. Exposures: COVID-19 pandemic and SARS-CoV-2 infection. Main Outcomes and Measures: The primary outcome was incidence of T1D and T2D, and secondary outcomes included the rate of diabetic ketoacidosis (DKA) and association of new-onset diabetes with SARS-CoV-2 positivity. Results: The study included 2599 patients with T1D (mean [SD] age, 12.0 [4.8] years; 1235 [47.5%] male) and 11 040 patients with T2D (mean [SD] age, 16.0 [2.8] years; 6861 [62.1%] male). During the pandemic, the incidence rate ratios were 1.19 (95% CI, 1.10-1.29) for T1D and 1.41 (95% CI, 1.36-1.46) for T2D. The incidence rate of DKA at diagnosis increased during the first pandemic year compared with the prepandemic period (T1D, 42.8% [95% CI, 38.5%-47.0%] vs 31.3% [95% CI, 29.0%-33.7%], respectively; T2D, 6.0% [95% CI, 5.0%-7.1%] vs 2.9% [95% CI, 2.5%-3.3%], respectively) but returned to prepandemic levels in the second pandemic year (T1D, 34.5% [95% CI, 30.6%-38.5%]; T2D, 3.2% [95% CI, 2.6%-3.9%]). The hazard ratio for new-onset diabetes associated with SARS-CoV-2 positivity was 0.44 (95% CI, 0.17-1.13) for T1D and 1.08 (95% CI, 0.74-1.57) for T2D. Conclusions and Relevance: These findings suggest that the incidence and severity of T1D and T2D among South Korean youths increased during the COVID-19 pandemic. The cohort analysis does not support SARS-CoV-2 infection itself as being directly associated with incident diabetes.
