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 results subsection “Characteristics of responders by group” on page 1592 should have read: “Table 3 shows that Asian doctors who qualified in the United Kingdom (group 1) were significantly younger than doctors in the other groups. Also, Asian doctors had a higher proportion of patients who were from deprived wards.” In table 4 (top of page 1593) the prescribing variables adjusted for confounding factors were calculated incorrectly. The correct values are given below. However, the overall conclusions—that there were no differences between the three groups in their prescribing practice—remain valid as, after Bonferroni correction, no differences in mean generic prescribing were detected (see table 1).
