In this study, we used AIC to select the degrees of freedom, and used residual deviance to choose both cold and hot thresholds, but used a priori arguments to choose cross-basis type and maximum lag day.
There are also some issues in the selection of the DLNM, such as cross-basis type, maximum lag day, and degrees of freedom (knots and placement) for exposure and lag (Armstrong 2006; Gasparrini et al. 2010).
Further, like other published results of cumulative effects of total PM, in the present study we also found that the cumulative impact of traffic-related PM2.5 was greater than any single lag considered, suggesting that the consideration of any single lag, even the maximum lag day, tends to underestimate the total distributed-lag health effects.

In general, the optimal maximum lag time should be placed at the day where the shape of the temperature mortality curve will not change significantly even when longer lag time is applied.
Temp t l is a matrix produced by DLNM to model non-linear and distributed lag effects of ambient temperature over the current day (lag 0) to lag l days, and β is vector of coefficients for Temp t,l ; The maximum lag l was set to 25 days to explore the lag structure of temperature effect [ 17].
In the sensitivity analysis, the maximum lag was changed to 5, 15, and 20 days.
In our analysis, associations with single-day lags were strongest for lag day 1, and associations were significant for the first 3 lag days only.
A negative effect of relative humidity at lag 1 day and positive effects were found on lag 5 7 days, and an adverse effect was observed for sunshine at lag days 3 4 (ER=−0.71%, 95% CI: −1.25 to −0.17% on lag day 4).
To define maximum lag, we assume a maximum incubation period of the CD of I days.
We present only the maximum lag length (see Appendix 2).
Maximum lag is automatically selected based on Schwarz information criterion.
