Efficacy and safety of rivastigmine in patients with Alzheimer's disease: international randomised controlled trial

We have recently been alerted to two small errors in a table in this paper by Michael Rösler and colleagues (1999;318:633-8). In the intention to treat analysis for high dose rivastigmine, the P value versus placebo for the Alzheimer's disease assessment scale (cognitive subscale) should be 0.011 [not <0.1] and for the progression deterioration scale should be 0.07 [not <0.1].
