The mean 128 cases 50.5 micrograms/liter that controls 54.3 (p = 0.012 for difference). When residual variation consumption as well four other possible confounders allowed multiple logistic model, less than 45 associated relative cancer 3.1 (95% confidence interval, 1.5-6.7, p 0.01). These support hypothesis deficiency increases certain cancers middle-aged persons.
