Table 2 Median time to positivity of the bottles comparing different contamination models and different fluids

From: A simple and easy in vitro model to test the efficacy of IV lines' needleless connectors against contamination

Fluid	MTP (IQR), h			p
Fluid	Hands	0.5 MF SA	0.05 MF SA	p
Saline	76.25 (65.95 to 125.00)	104.92 (45.96 to 239.94)	240.20 (154.82 to 360.00)	0.041 ^a
Propofol	74.91 (51.44 to 98.99)	147.89 (66.03 to 236.58)	66.11 (58.01 to 69.11)	0.24
