Reported differences are between subjects with a CrC ≤45 ml/min and the reference group (>60 ml/min) and are expressed in percent with a 95% CI.
There were 330 subjects considered appropriate candidates for reperfusion therapy by ECG criteria (≥1-mm ST-segment elevation in two leads): 32 with a CrC ≤45 ml/min, 63 in the 45- to 60-ml/min category, and 235 with a CrC >60 ml/min.
There were no significant between-group differences by χ2.
