ORs for brain tumours with level of total cumulative specific RF energy (TCSE) exposure (in joules per kilogram) in subjects with tumour centre estimated by a neuroradiologist or computer algorithm, excluding non-regular users. n these analyses, the lowest quintile of TCSE is used as the reference category
