Effectiveness of low dose cyproterone acetate compared to standard dose in feminizing hormone treatment: a single institutional retrospective pilot study.

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: Data regarding the effectiveness of low-dose cyproterone acetate (CPA) in testosterone suppression as feminizing hormone therapy (FHT) in individuals assigned male at birth (AMAB) are sparse. Aim: To assess the effectiveness in testosterone suppression using low-dose CPA (<25 mg/day) compared to standard-dose CPA (25-50 mg/day) in FHT. Methods: A retrospective cohort study of 59 individuals AMAB using CPA was done at a tertiary care center in Bangkok, Thailand between January 2014 and July 2022. Outcomes: The main outcomes included a median time when the testosterone was suppressed (<50 ng/dL), the proportion of individuals AMAB who achieved the targeted testosterone level at 3 months, and the testosterone level at each follow-up. Changes in clinical data were assessed. Results: Among 59 individuals AMAB, 37 initiated CPA with available testosterone levels at the 3-month follow-up. Twenty-two individuals AMAB started with low-dose CPA (12.5 mg/day), and 15 individuals AMAB started with standard-dose CPA. The median time to reach targeted testosterone was 3 months in both groups (adjusted hazard ratio 0.60, Clinical Translation: This study supports a paradigm shift toward using lower-dose CPA in FHT. Strengths and Limitations: This is one of a few studies showing the effectiveness of low-dose CPA in testosterone suppression within 3 months. Limitations include a small sample size and missing data. Conclusions: Testosterone suppression is comparable between CPA 12.5 mg/day and the standard dose in FHT.
