[Behavior of calcemia in breast malignancy. Note I (author's transl)].

The authors report a statistical investigation conducted in 95 patients with mammary carcinoma, designed to show the behavior of calcemia in the course of this malignancy. The data were analyzed statistically by the binomial test, the scatter of values (F test of Snedecor), and the t test of Student. The authors confirmed the existence of a statistically significant alteration of calcemia only in the group of patients with metastasis to bone versus control subjects; conversely there was no significant difference of distribution in the various groups in regard to values beyond those given as normal.
