Estimated incidence rate ratios (IRRs) and associated 95% confidence intervals and P-values for daily admissions for renal diseases in relation to an increase in daily temperature (maximum, minimum and average) per 1°C during the warm seasons (October – March) in Adelaide from 1 July 2003 to 31 March 2014. Both emergency department (ED) and inpatient admissions were included
