COPD (chronic obstructive pulmonary disease): model A, basic model, unadjusted; model B, adjusted for linear secular trend; model C, additional adjustment for seasonality, day of the week, temperature, flue and acute respiratory infections; model D, additional adjustment for pollution levels; model E, additional adjustment for tobacco consumption prevalence; model F, full model adjusted for quadratic secular trend.

Asthma: model A, basic model, unadjusted; model B, adjusted for linear secular trend; model C, additional adjustment for seasonality, day of the week, temperature, flue and acute respiratory infections; model D, additional adjustment for pollution levels; model E, additional adjustment for pollen count; model F, additional adjustment for tobacco consumption prevalence.
