**3.3 Creatinine clearance of subjects**

The mean creatinine clearance in the CRF and control groups was 9.8 + 6.7mls/min and 126.2 + 7.4 mls/min respectively. There was a statistically significant difference between both means (p < 0.05).

Table 4 shows the distribution of subjects according to creatinine clearance. In the CRF group, 47 (90%) had ESRD, with creatinine clearance < 15mls/min, 4 (8%) had creatinine clearance of 15 – 29mls/min, and 1 (2%) had creatinine clearance 30 – 59mls/min. All controls had creatinine clearance > 95mls/min (see Table 4).
