Interpret the numerical results succinctly. Let X = ln ( ^ CIR ) = 0.8776 ^ Var ( X ) = N 1 a a N 1 + N 0 b b N 0 = 0.00583 + 0.0266 = 0.03243 95% CI for ln(CIR): X ± 1.96 ^ Var ( X )= 0.8776 ± 0.353 =( 0.5246,1.2306 ) 95% CI for CIR: e X ± 1.96 ^ Var ( X ) =( 1.69,3.42 ) These data are consistent with CIR ranging from 1.69 to 3.42 with 95% confidence over the 22-year study period, assuming no confounding, selection bias or information bias. d. Calculate the cumulative incidence difference for oral or bladder cancer from cigarette smoking, and the relevant 95% confidence limits. Interpret the numerical results succinctly.
Let X = ^ CID = 0.0217 N N b ( ¿¿ 0 b ) N 0 3 = 0.0000084 + 0.0000066 = 0.0000150 a ( ¿¿ 1 a ) N 1 3 + ¿ ^ Var ( X ) = ^ Var ( ^ CID ) = ¿ 95% CI for CID is: X ± 1.96 ^ Var ( X )= 0.0217 ± 0.00759 =( 0.0141,0.0293 ) These data are consistent with CID ranging from 0.0141 to 0.0293 over the 22-year study period with 95% confidence, assuming no confounding, selection bias or information bias.
