  1. Note: n number of subjects, SkelDys Skeletal dysplasia, a = Age, gender, and place of residence control subjects for the particular diagnosis. P-values are from Pearson Chi-Square -test’s for nominal scale variables and Independent-Samples T-test for interval scale variables; 95% confidence intervals are from t-tests; Cardiovascular diseases = heart disease, coronary artery disease, hypertension, other cardiovascular disease; Immune system problems/diseases = more infections than normal, asthma or other pulmonary disease, allergies or tumor disease; Excretory problems = some intestinal disease, difficult constipation or long lasting diarrhea; Urinary problems = incontinence or other problem related to urination
