Table 2 Descriptive statistics for observed temperature values in Porto Metropolitan Areas (PMA) and Lisbon Metropolitan Areas (LMA), used in the models for the period 1986–2000 and validating period 2001–2005 together with the estimated relative risks (RRs) values at averages, 1st and 99th percentiles temperature values

From: Bootstrap approach to validate the performance of models for predicting mortality risk temperature in Portuguese Metropolitan Areas
