Each patient was included only once, using the diagnostic or procedural code in the primary field in the first occurrence for allocation to a clinical group.
We use patch-occupancy models to quantify the contribution of sub-populations to disease occurrence ("risk") and model allocation strategies for a limited number of vaccine doses that prioritize villages based on their size, risk, or the reduction in risk for the entire population that would result from vaccination.
Despite the differences between self-reports, hospital discharge codes and verified events, neither the source of the event nor the level of adjudication substantially altered the relationship between treatment allocation and occurrence of either MI or stroke.
Public health agencies, medical care delivery systems, and clinicians all depend on accurate and timely information about disease occurrence to guide planning, resource allocation, and case management.

Research assistants, who are blinded to group allocation, check for falls occurrence on a weekly basis by reviewing medical records and interviewing staff and participants and their families.
Rates of physician-only interventions were significantly higher in the group allocated to physician care, with occurrence of such interventions in the paramedic only allocation group reflecting the non-compliance rate.

The occurrence of lymphedema, regardless of treatment group allocation, is considered an 'adverse' event.
Allocation concealment will prevent the occurrence of selection bias before the interventions are provided to the participants [ 36].
