The post-event period is typically one or just a few days after the event day.
Therefore, here we report only results for exposure to PM10 on the event day compared with temperature-matched control days.
Exposure was characterised for each health event using the nearest monitoring station to the place of residence, with the condition that exposure information was not missing on the event day and on ≥90% of days within each risk period (as defined in the analysis section).
If in addition, the control days are chosen close to the event day, personal characteristics that vary slowly over time are also controlled by matching.
By using control days close in time to the event day, there is no confounding by slowly varying personal characteristics, because each subject is the perfect match for himself.
Analyses of lagged exposures suggested that exposure on the event day was more important than exposure during the 3 days preceding the event.
If in addition, the control days are chosen to be close to the event day, slowly varying subject characteristics are also controlled by matching [ 22].
Claims were sorted by person identifier and service dates, and from this an event day-level file was created.
