1 · What the graph read from it

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.

2 · The registry

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

Background: Children and adolescents with type 1 diabetes mellitus (T1D) are at increased risk of developing additional autoimmune diseases. However, data on the frequency, spectrum, and timing of these comorbidities in long-term pediatric cohorts remain limited. This study aimed to evaluate the prevalence, clinical characteristics, and temporal relationships of autoimmune diseases in children and adolescents with T1D, as well as to identify factors associated with their occurrence. Methods: This retrospective study included 639 children and adolescents with T1D who were followed at a tertiary pediatric endocrinology center between January 2004 and October 2018. Demographic, clinical, laboratory, and autoantibody data were reviewed. Autoimmune diseases were identified through routine annual screening and clinical follow-up. Temporal relationships between T1D and autoimmune disease diagnoses were analyzed. Multivariable logistic regression was used to assess factors associated with additional autoimmune diseases. Results: At least one additional autoimmune disease was identified in 120 subjects with diabetes (18.8%). The most frequent comorbidities were autoimmune thyroiditis (AIT, 12.7%) and celiac disease (CD, 5.9%), followed by vitiligo (1.3%), autoimmune gastritis/pernicious anemia (0.15%), and autoimmune hepatitis (0.15%). Female sex was independently associated with the presence of additional autoimmune diseases (OR = 1.61, 95% CI 1.07-2.41, Conclusion: Autoimmune comorbidities, particularly AIT and CD, are common in pediatric T1D, with most diagnoses occurring within the first two years around diabetes onset. These findings support intensified and closer screening-especially during the early disease course and in female subjects with diabetes-to enable earlier detection and improved long-term management. This study provides valuable epidemiological data from Türkiye and contributes to global pediatric T1D literature.
