Special modules of PoP allow for the scheduling of study participants for follow-up and for the allocation of treatment assignments in randomized trials. PoP was developed at the Epidemiology Data Center by the Systems and Programming group. The software is written in the C programming language and has taken more than 10 person-years to develop. PoP also is used to support other NIH sponsored projects for single-center data entry. PoP requires DOS on at least an 80286 microcomputer.
PoP is made available for use by other researchers, upon request.
The process is generally initiated at the coordinating center. To enhance security the remote center must return a call to the coordinating center before information can be transferred. HyperPoP has been a reliable and integral resource for numerous EDC research initiatives. HyperPoP was written by the Systems and Programming group using the HyperAccess product by Hilgraeve. It was designed specifically to provide central data management capabilities internally at the EDC for projects implementing the PoP Data Entry System remotely at clinical centers.
