Table 1: Results of the calculations of the multiple linear regression fits performed for each of the 2 allergic pathologies of this study (named with the CIAP-2 codes), in each of the 11 zones of the Palinocam Network, which constitute the geographical reference of this study, for the year 2014. The explanatory variables (air pollutants and pollen types) are also shown in the different models. Shaded in light blue are the equations with good correlation (R\({}^{2}\) > 30%).
