Odds Ratios Indicating (a) the Effect of Staffing in Various Nurse Work Environments, and (b) the Effect of the Nurse Work Environment at Various Staffing Levels

(a) When the Hospitals Nurse Work Environment is -	The Odds Ratio Indicating the Effect of Staffing is -
	On Mortality	On Failure-to-Rescue
Two standard deviations below the mean	0.982	0.969
One standard deviation below the mean	1.010	1.004
At the mean	1.039*	1.039*
One standard deviations above the mean	1.070*	1.076*
Two standard deviations above the mean	1.101*	1.115*

(b) When the Hospitals Patient-to-Nurse Ratio is -	The Odds Ratio Indicating the Effect of the Nurse Work Environment is -
	On Mortality	On Failure-to-Rescue
Two patients per nurse above mean	0.981	0.975
One patient per nurse above mean	0.952*	0.958*
At the mean	0.926*	0.925*
One patient per nurse below mean	0.900*	0.893*
Two patients per nurse below mean	0.875*	0.863*
