Effect of doctors' ethnicity and country of qualification on prescribing patterns in single handed general practices: linkage of information collected by questionnaire and from routine data

Two errors occurred in this paper by Paramjit S Gill and others (12 December, pp 1590-4). The first sentence in the resultssubsection "Characteristics of responders by group" on page 1592should have read: "Table 3 shows that Asian doctors who qualifiedin the United Kingdom (group 1) were significantly younger thandoctors in the other groups. Also, Asian doctors had a higherproportion of patients who were from deprived wards." In table4 (top of page 1593) the prescribing variables adjusted for confoundingfactors were calculated incorrectly. The correct values are givenbelow. However, the overall conclusions $---$ that there were no differencesbetween the three groups in their prescribing practice $---$ remainvalid as, after Bonferroni correction, no differences in meangeneric prescribing were detected (see table 1).
