Behaviour of [Na/Fe] as function of [Fe/H] of the metal- poor, Li-rich stars (same symbols of Fig. 3) in comparison with the NLTE abundances for metal-poor Milky Way stars (grey circles) from Andrievsky et al. (2007) and Lombardo et al. (2022). The [Na/Fe] abun- dance ratio of HE 0057-5959 plotted here accounts for NLTE effects for Na abundance only. The position of the Li-rich star by Kowkabany et al. (2022), the most Li-rich discovered so far, is marked.
