Frequency and Predictors of Self-Reported Hypoglycemia in Insulin-Treated Diabetes

Table 3

Results of nonparametric tests Spearman’s correlation (to calculate correlation coefficient) and Wilcoxon signed-rank test (to assess significance with value) for association of continuous independent variables with frequencies of hypoglycemia and severe hypoglycemia.
