Successful Treatment of Bexarotene-Induced Central Hypothyroidism.
Article in JCEM case reports, 2024. 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
The synthetic retinoid bexarotene (BXT), used in the treatment of cutaneous T-cell lymphoma (CTCL), has been associated with central hypothyroidism due to suppression of thyrotropin (TSH) secretion and upregulation of peripheral thyroxine (T4) and triiodothyronine (T3) metabolism. We present a case of a 41-year-old man with CTCL who developed central hypothyroidism within 1 month of receiving BXT. He required sequential uptitration of levothyroxine (LT4) over 15 months, and free T4 (FT4) and total T3 levels were normalized by a daily regimen of LT4 600 mcg and liothyronine (LT3) 15 mcg. While almost all patients regain normal hypothalamic-pituitary-thyroid axis function after cessation of BXT, there are limited data regarding LT4 and LT3 dosing required to adequately treat central hypothyroidism in patients on BXT. Our patient required an LT4 dose approximately 2.8 times the calculated weight-based dose and LT3 supplementation, demonstrating a large LT4/LT3 combination dose may be required to compensate for BXT-induced central hypothyroidism.
