Natural course of subclinical hyperthyroidism in primary care in the Netherlands.
Article in European thyroid journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Subclinical hyperthyroidism (SHT), a low serum thyroid-stimulating hormone (TSH) and normal free thyroxine (FT4) concentration, has potential health implications, yet the epidemiology and factors influencing its natural course in a primary care setting remain unclear. Objectives: To investigate the incidence and natural course of SHT in primary care and assess guideline adherence to follow-up recommendations within Dutch primary care. Methods: Using a retrospective cohort design in general practitioner data from the PHARMO Data Network in the Netherlands (2012-2021), patients with biochemically confirmed SHT were followed to assess progression to hyperthyroidism, recovery, or persistence. Adherence to the Dutch primary care SHT guideline was evaluated. Results: The SHT annual incidence was approximately 200 per 100,000 person-years. Among the 11,163 SHT patients, 47% recovered, 11% persisted, and 8% progressed to overt hyperthyroidism over a median follow-up of 5 years. Lower TSH (<0.1 mU/L) and female sex were associated with lower odds of recovery (OR for TSH <0.1 mU/L: 0.50, 95% CI: 0.43-0.58; OR for women: 0.82, 95% CI: 0.70-0.96) and higher odds of progression to overt hyperthyroidism (OR for TSH <0.1 mU/L: 2.36, 95% CI: 1.97-2.83; OR for women: 1.69, 95% CI: 1.32-2.17). Guideline adherence evaluation showed that 33% received follow-up TSH measurement within 6 months, and 4% underwent TSH-receptor antibody testing. Conclusion: This study highlights that a small subset of SHT patients progress to overt hyperthyroidism. Factors increasing the odds for progression included lower baseline TSH and female sex. Our findings indicate a need for improved guideline adherence.
