Abstract: Systems, methods, and devices identify members of a cohort, as one example. In embodiments, medical professionals may seek to identify patents who suffer from, or are likely to suffer from, a condition, even if patients are not associated with a diagnoses or a recorded description of the condition, or medical professionals may seek to confirm the inclusion of members in a cohort. Embodiments include considering hypothetical factors that may indicate whether a patient has a condition, performing regression analyses to obtain a set of initial cohorts and likelihoods that they will experience the condition, and user interaction(s) to identify members, for example patients with a higher likelihood of developing a condition. Outputs include, in embodiments, treatment plans or updates for a patent such as medications or appointments, tests to be performed on physical samples, or input(s) for a manufacturing process, such as three-dimensional printing using biological or other materials.
