Suppose a value of 130 mg/dl or higher was considered positive and the prevalence of undetected diabetes remained the same as questions 2-3 ( available for refrence below)how would you predict sensitivity (se) would be affected by this change? why? guess without calculation! sensitivity would be [ select one] ["increased", "no change", "decreased"] because [ select one] ["tp", "tn", "fp", "fn"] will decreasehow would you predict specificity would be affected by this change ? why? guess without calculation! specificity would be [ select one] ["decreased", "", "increased", "no change"] because [ select one ] ["tp", "fn", "fp", "tn"] will increase. compare sensitivity and specificity and observe how the number in cell a, b, c, and d is changing when you change the cutoff point from high to low (from 180 mg/dl to 130 mg/dl) .sensitivity = tp /(tp + fn) = a/(a+c)specificity = tn /(fp + tn) = b/(b+d
