Table 6 Predicted trend of wood densities according to a combination of different drought conditions (i.e., SPEI / Drought intensity) and levels of LER for all species. MWDI, EWDI, and LWDI columns identify the trend estimated by the model by fixing TRW = 1.35 mm, cDBH = 27.45 cm in the case of beech, TRW = 1.79 mm, cDBH = 40.02 cm in the case of fir, and TRW = 1.73 mm, cDBH = 36.76 cm in the case of spruce. The values of MWDI, EWDI and LWDI in bold refer to the cases when the estimated coefficients of LER*SPEI resulted as statistically significant in our models
