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

Latent autoimmune diabetes in adults (LADA), also known as type 1.5 diabetes, is an autoimmune diabetes that shares genetic, immunological, and clinical features with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) and is commonly misdiagnosed as type 2 diabetes. Thyroid disease in patients with LADA was estimated to be 17.7%. We are reporting a case of Hashimoto's thyroiditis (HT) in an obese patient having hyperglycemia with poor response to regular management. We reported this case as a reminder that the presence of an autoimmune condition in a patient with hyperglycemia, autoimmune diabetes, must be considered. A 40-year-old female with a body mass index of 35.2 kg/m² complains of fatigability and exercise intolerance. Her HbA1c was 7.9; she was first diagnosed with T2DM and started on the oral hypoglycemic agent metformin. Her HbA1c increased despite her admitting that she was adherent to her medications and the dietary regimen. She reported anterior neck swelling. The thyroid ultrasound showed a heterogeneous texture of the thyroid gland. Anti-thyroid peroxidase antibody titer and anti-thyroglobulin antibody titer were high. Her anti-TSH receptor antibody titer was within the normal range. Thus, she was diagnosed with autoimmune HT and started on thyroxine. Both parents had T2DM, and she was never admitted to the hospital with ketoacidosis. Failure to control her diabetes, along with the recent diagnosis of autoimmune HT, raises the suspicion of LADA. Her anti-glutamic acid decarboxylase (GAD) antibody then came back positive, and her C-peptide level was low. She was shifted to an insulin basal and bolus regimen, and her last HbA1c was 5.7. The case highlights the importance of considering LADA in patients with poor glycemic control despite standard T2DM therapy, especially when autoimmune diseases are present: positive anti-GAD antibodies, low C-peptide, and improved outcomes with insulin support the diagnosis. Early detection is crucial for effective management and preventing disease progression.
