Multipanel overview of the Li abundance for the eight SFRs (Cha I, η Cha, Lupus, Taurus, Orion OB1a, Orion OB1b, σ Ori, and CrA). For each region, the left subpanel shows NLTE-corrected Li abundance as a function of effective temperature. Red squares and black dots represent the A(Li) values derived from $E{W}_{\text{Li}}^{\text{Fe}}$ and $E{W}_{\text{Li}}^{\text{veil+Fe}}$, respectively. K-type and M-type stars are plotted with filled and open symbols, respectively. The Li isochrones by Baraffe et al. (2015) in the 2–20 Myr range are overlaid with dot-dashed lines. Arrows refer to lower (stars whose final A(Li) value exceeds 4.0 dex, see text) or upper (due to the unresolved contribution of the FeI λ 6707.4 line) limits. Each right subpanel displays the histogram of the corresponding A(Li) distribution, corrected for veiling.
