Table 4 The comparison of our patients and cohort from the Karaszewski et al. population study [14]. For the comparison, we excluded from our cohort four patients with a history of thyroid disease

From: Incidence of thyroid nodules in early stage autosomal polycystic kidney disease

P-values for our cohort versus cohort from population study are calculated using independent-sample t-test in case of normal distribution, Mann-Whitney U in case of non-normal distribution, and chi-square test with Yates’s correction in case of categorical data. n number of patients, SD standard deviation, TG thyroid gland, f1 female patients from our cohort, f2 female subjects form Karaszewski et al. study, m1 male patients from our cohort, m2 male subjects form Karaszewski et al. study, f1 vs. f2 the comparison of the groups of women, m1 vs. m2 the comparison of the groups of men, V volume, TN thyroid nodules, MTN multiple thyroid nodules, TSH thyroid-stimulating hormone. athe comparison of the sex ratio in both cohorts
