Patients recruited onto the ICON8 trial were required to meet the following criteria:
*Direct measurement of GFR by a radioisotope method is highly recommended in all cases but it is acceptable for GFR to be measured or calculated according to local practice (see Appendix 4). However, if the calculated creatinine clearance is <60ml/min then it is mandatory that a formal measurement of the GFR is performed (using either a 24 hour urine collection or an isotopic clearance)
