: BKB owns shares in Royal Dutch Shell and in Scottish and Southern Energy and her spouse has a deferred Shell pension. All other authors declare they have no potential conflict of interest.
: Approval for the ISAAC Phase Three study was obtained from local ethics committees or other appropriate bodies. An information letter was sent home via pupils to their parents/guardians in advance of the study taking place in school. In most study centres, consent was passive; i.e. parents or guardians were asked to contact researchers if they or the study subject did not want to take part and no such contact was taken as consent (Ellwood et al.
