Table 3 Effect of intervention on primary and secondary endpoints

From: Routine resite of peripheral intravenous devices every 3 days did not reduce complications compared with clinically indicated resite: a randomised controlled trial

Outcomes 3-Day Routine Change Group (n = 177) Clinically Indicated Change Group (n = 185) RR (95% CI), PValue
