Drug treatment of Parkinson's disease

An author's error occurred in the letter in this cluster by Niall Quinn (24 June, p 1668). The penultimate sentence of the first paragraph should have read: “Scores below the lower limit of the 95% confidence interval for controls were found in 75% [not 51%] of patients with idiopathic Parkinson's disease, 31% of those with multiple system atrophy, 20% of those with progressive supranuclear palsy, and none of the seven with corticobasal degeneration who were tested.”
