Two errors in table 3 of this paper by Amanda I Adler and colleagues (12 August, pp 412-9) persisted to final publication. In the fifth column (Updated mean SBP, Decrease in risk) the values for microvascular disease should read 13 (9 to 16) [not 13 (9 to 26)] and those for heart failure should read 12 (4 to 19) [not 15 (4 to 19)].
