Sensitivity analysis altering the positioning of the knots (k1 and k2) in the exposure response dimension and the number of degrees of freedom for the NS representing the lag response function (df1) and per year for seasonality (df2).

The estimated attributable mortality (attr) and an upper (ub) and lower (lb) bound (derived from monte-carlo simulations) are given for each model and the model deviation (summed across the regions). The model with the lowest deviance is highlighted and is the model selected. (XLSX)
