Fig. 4From: Recovery of serum testosterone levels is an accurate predictor of survival from COVID-19 in male patientsThe luteinizing hormone (LH)-androstenedione axis is not significantly perturbed in male COVID-19 patients. A Determinations of serum LH and androstenedione levels in samples collected at admission, grouped by eventual outcomes. Pair-way between-group comparisons were performed by t test. B Longitudinal determinations (≥ 3 samples) of serum LH, androstenedione, and testosterone levels, analyzed as in Fig. 3. Comparisons of trajectories (linear regression slopes) were performed by two-way ANOVABack to article page
