Slot: Address Period Alignment (address_period_alignment)

How the patient's location-over-time (the spatial axis of trajectory resolution) was modelled.

Tier: recommended

Why this slot matters

Assuming a single static address smears home-location exposure across days the patient was actually elsewhere; how location-over-time was modelled changes which days get which values and can bias exposure estimates.

In plain terms

People move house and travel, so "where the patient was" changes over time. This records whether the study used one fixed address, a full address history, or accounted for known trips away from home.
