Association between sensitivity to thyroid hormone indices and frailty in the elderly: a cross-sectional study.
Article in Frontiers in endocrinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: Frailty is a prevalent geriatric syndrome that affects several systems and lacks accurate evaluation indications. Previous studies on the association between thyroid function and frailty have contradicted. This study introduced the thyroid hormone sensitivity indices to analyze their connection with frailty and evaluate its usefulness in assessing frailty. Methods: A total of 1030 Chinese elderly individuals were included. The FRAIL scale was utilized to assess the frailty status of subjects. The thyroid hormone sensitivity indices, including the following: Thyrotrophic Thyroxine Resistance Index (TT4RI), Thyroid Stimulating Hormone Index (TSHI), Thyroid Feedback Quantile-based Index (TFQI) and Free Triiodothyronine/Free Thyroxine (FT3/FT4), were calculated based on thyroid function. A multivariate logistic regression analysis assessed the association between frailty and these markers. Results: The study findings indicated that frailty groups exhibited lower levels of FT3 and TSH compared to non-frailty groups. Additionally, the central sensitivity index of thyroid hormone [TFQI(FT3)] and the peripheral sensitivity index (FT3/FT4) were also lower in frailty groups. Following the adjustment for multiple variables, FT3 (OR=0.640, 95%CI: 0.534-0.768, Conclusion: Serum FT3 and TSH declined in frail patients, whereas there was no alteration in serum FT4. Both the decrease of central sensitivity index of thyroid hormone, TSHI and TFQI(FT3), and peripheral sensitivity index, FT3/FT4, were associated with frailty assessed by FRAIL scale. Specific thyroid measures, especially FT3, TFQI(FT3) and FT3/FT4, would be served as easily measurable indications that are essential for evaluating frailty.
