Evaluation of dihydrotestosterone levels and total testosterone to dihydrotestosterone ratio with clinical symptoms and metabolic parameters in patients with polycystic ovary syndrome.

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
backgroundPolycystic ovary syndrome (PCOS) is a clinically heterogeneous endocrine disorder with lifelong health risks. Androgen excess, particularly testosterone, plays a key role in the pathophysiology of PCOS. Dihydrotestosterone (DHT) is an active metabolite derived from testosterone, and the total testosterone (TT) to DHT ratio is known as a potential marker of androgen metabolism, which can be used for evaluation of metabolic phenotype. This exploratory study aims to evaluate the association between DHT levels and TT/DHT ratio with the metabolic parameters and clinical features of PCOS patients.
methodsThis cross-sectional study was conducted on 30 patients diagnosed with PCOS based on the Rotterdam 2003 criteria. Clinical, metabolic, and biochemical parameters were assessed. The association between DHT levels, TT/DHT ratio, and clinical as well as metabolic features was analyzed using ANOVA, Spearman correlation, and independent sample t-tests, with a significance threshold of p < 0.05.
resultsThe TT/DHT ratio was significantly lower in patients with regular menstruation compared to those with oligomenorrhea and amenorrhea (p < 0.05). A moderate positive correlation was found between DHT levels and BMI (r = 0.487, p < 0.05), while fasting blood sugar (FBS) was significantly correlated with the TT/DHT ratio (r = 0.376, p < 0.05). Patients with insulin resistance had a significantly higher TT/DHT ratio compared to those without insulin resistance (p < 0.05), whereas DHT levels did not differ significantly between these groups.
conclusionThe TT/DHT ratio could be a useful biomarker to identify PCOS patients with more severe metabolic issues.
