Need for Data Capture Software Convenient uniform data entry method – Stateless web-based – Secure WUSM HIPAA compliant centralized data store. Easy to use multi-purpose clinical database – Not Excel, Not Access, Not 3-4 composition notebooks somewhere on the top shelf Mostly self service Reduce data “cleaning” effort during analysis.

Calculations Simple [weight]*10000/([height]*[height]) Complex Calculating the Mean of groups with null valid range includes zero The following equation will calculate the Mean of a list of variables ( (if(Math.abs([A])>0,[A],0)) +(if(Math.abs([B])>0,[B],0)) +(if(Math.abs([C])>0,[C],0)) ) / ( (if(Math.abs([A])>0,1,if([A]=0,1,0)) +if(Math.abs([B])>0,1,if([B]=0,1,0)) +if(Math.abs([C])>0,1,if([C]=0,1,0)) )
