Most Score Calculation

Y =

-3.8390 + (0.1570 x male gender)
+(0.0712 x CCI)
+(0.0532 x ADLS)
-(0.1720 x GCS)
+(0.0678 x age)
-(0.0004 x (age x age)
+(0.0175 x heart rate)
+(0.0631 x respiratory rate)
+(0.0289 x white blood cell count)
-(0.0410 x systolic blood pressure)
+(0.000121 x (systolic blood pressure x systolic blood pressure)

Where R is the risk of bad outcome and the categorical variable gender, is coded female=0 and male=1.

ADL Score:
- 0 - independent
- 3 - minor dependence
- 6 - major dependence
CCI - Charlson Comorbidity Index
Heart Rate(HR), Respiratory Rate (RR), White Blood cell Count (WBC), systolic Blood Pressure (sBP) - are continuous data

How to calculate R:

The cut-off probability for R is 0.088

+Most Score Calculation
-After some searching I don't actually think we have the calculation for the MOST score documented on the wiki. Julie, could you please put it up here? Please include what the meaning of the calculated score is.
