cumulative mean
1.Patients treated with ergot derivatives who had grade 3 to 4 regurgitation of any valve had received a significantly higher mean cumulative dose of pergolide or cabergoline than had patients with lower grades.
2.Postoperative mean ABI increased from 0.29 to 0.84. The limb salvage rate was 100% and the cumulative patency rates of 1,2,3,4 and 5 years were 92%, 87%, 82%, 72% and 65% respectively by the lifetable analysis.
3.Using Monte-Carlo random sampling method, we establish the simulation model of the automobile braking function failure, set up the Fault Tree Analysis(FTA) simulation program SFTA, and work out the Mean Time Between Failure (MTBF) cumulative failure probability and importance of bottom events of vehicle system.
4.The results showed that airway responsiveness reduced in the BDP group, whereas no change occurredin the placebo group. The geometric mean of the amount of cumulative dose (D_(min)) incre ased significantly from 0.116u to 0.658u (p<0.01) in 9 cases treated with BDP aerosol (300—450μg/day).
