Association between free T3 and sarcopenia in euthyroid older patients with Hashimoto's thyroiditis.

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
Purpose: Growing evidence suggests that thyroid hormones play an important role in the process of sarcopenia during aging. The aim of our study was to investigate whether thyroid hormones have an association with age-related sarcopenia in euthyroid geriatric patients with Hashimoto's thyroiditis (HT). Methods: A total of 442 euthyroid older patients with Hashimoto's thyroiditis were included in this cross-sectional study. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia (AWGS) 2019 criteria. Body composition, grip strength and gait speed were assessed in participants. Concentrations of thyroid hormones were determined by immunoassays. Logistic regression analyses were carried out to assess the association between free T3 (FT3) levels and sarcopenia risk. Results: Compared to non-sarcopenic patients, FT3 levels were found to be lower in the sarcopenic group (2.92 pg/ml vs 3.00 pg/ml, p<0.05). Multiple linear regression analysis showed a significant positive association between FT3 and hand grip strength, gait speed, skeletal muscle mass. Multivariable logistic regression analysis showed that FT3 levels were independently associated with sarcopenia (odds ratio 0.533 [95% confidence interval 0.343, 0.829], p=0.005) and low gait speed, low hand grip strength, low skeletal muscle index. Conclusion: Higher FT3 levels within normal range was positively associated with skeletal muscle mass, hand grip strength and physical function in elderly euthyroid individuals with HT.
