Transition from Hashimoto thyroiditis to Graves's Disease: an unpredictable change?
Article in Endocrine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeHashimoto thyroiditis and Graves's disease are two related autoimmune disorders, representing the leading causes of hypothyroidism and hyperthyroidism. Autoimmune hypothyroidism is generally irreversible but very rarely, some patients would shift to hyperthyroidism. The aim of the study was to seek for possible clinical predictors of the transition from hypo to hyperthyroidism in patients with Hashimoto thyroiditis and to outline their clinical phenotype.
methodsTwelve patients with overt autoimmune hypothyroidism who had at least one transition from hypothyroidism to autoimmune hyperthyroidism were compared with 294 consecutive patients with autoimmune hypothyroidism and 69 consecutive patients with autoimmune hyperthyroidism that accessed the outpatient clinic over six months. Demographic, hormonal data and autoantibodies titers were compared.
resultsPrevalence of smoking habit was significantly higher in switchers compared to controls. Switchers showed a significantly higher prevalence of personal and familial history of non-thyroidal autoimmune disorders. TSH levels were significantly lower in the switcher group during the hypothyroid phase and levothyroxine dose required was lower. TSH concentrations were significantly lower while free fT4 and free fT3 values were higher in GD patients compared to switchers during the hyperthyroid phase despite comparable TRAb levels. Prevalence and type of hyperthyroid symptoms and orbitopathy were similar between switchers and GD group. Mean dose of anti-thyroid drugs was significantly higher in GD patients compared to switchers. No differences were observed in the remission rate from hyperthyroidism between the two groups, despite switchers showed a significantly lower time-to-remission.
conclusionsConversion of Hashimoto Thyroiditis towards Graves' disease is a rare phenomenon which can occur almost at any time after the development of autoimmune hypothyroidism. Our findings suggest active surveillance of hypothyroid patients who require frequent reduction of levothyroxine during follow up and testing for TSHR antibodies in these patients.
