Serum Negative Chronic Autoimmune Thyroiditis (SN-CAT): A Case Report of Three Siblings Without Familial History of Autoimmune Thyroid Diseases (ATDs).
Article in Clinical case reports, 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
This case highlights the rare manifestation of a less prevalent form of chronic autoimmune thyroiditis, serum-negative chronic autoimmune thyroiditis, within a sibling cluster without detectable autoantibodies and unclear genetic links, with no familial history, challenging current understanding of autoimmune thyroid disease. Ultrasound findings remain crucial for diagnosis, underscoring the need for clinical vigilance in atypical pediatric hypothyroidism.
