Adjusted for age quartiles, month, sex, ethnic group, an interaction between ethnic group and sex (except for analysis of all ethnic groups combined) and school (random effect).
South Asian other and black other subgroups are not included in the table; therefore, the numbers in the subgroups do not add up to the main ethnic group totals for South Asians and black African–Caribbeans.
*p Value for heterogeneity between ethnic subgroups within broader ethnic groups, that is, South Asian and black African–Caribbean.
