这下我找到我们的分歧了.

In the relatively uncommon circumstance of vaccine matching the viral circulating strain and high circulation, 4% of unvaccinated people versus 1% of vaccinated people developed influenza symptoms (risk difference (RD) 3%, 95% confidence interval (CI) 2% to 5%). The corresponding figures for poor vaccine matching were 2% and 1% (RD 1, 95% CI 0% to 3%). 

我们的分歧在对1%的理解. 您的意思是一个百分点.

所有跟帖： 

• 发病率从2%下降到1%,可以说降了一个百分点,也可以说降了50% -TBz- ♂ (0 bytes) () 09/16/2010 postreply 14:55:05

• 在通常情况下，每注射免疫100人，才能有效防止一例流感证状，疫苗不能减少住院率和工作日损失同时造成瘫痪症 -医者意也- ♂ (1046 bytes) () 09/17/2010 postreply 04:49:34
