[Clinico-statistical notes on some characteristics of thyrotoxicosis].

Statistical analysis was used to examine certain environmental and biological aspects of thyrotoxicosis, specifically: marital status, occupation, sex, age of onset of menarche and menopause, number of pregnancies and miscarriages, blood groups (ABO, Rh system). The results showed a significant prevalence of non-married working women among patients suffering from thyrotoxicosis. They also showed that the patients under examination reach menarche at an earlier age and the menopause at a later age than a control group, and the figures were statistically significant.
