Because electronic health records are often missing information about patients, we developed and validated a tunable computer algorithm to identify subsets of patients whose data are relatively complete and therefore better suited for clinical research studies. A manuscript describing this study is currently under review:

Run the appropriate database script on your i2b2 CRC cell's database to identify patients whose data are relatively complete.
