(A–D) Distributions of socioeconomic features for the most (red) and the least (blue) affected LLMs, and remaining ones (white), identified using lockdown variable and $K=30\%$. For variables in panels (A–C), the Kruskal–Wallis test to assess statistical differences between the distributions of the classes of LLMs is significant at a level $\alpha =0.001$. For the variable in panel (D), it is not significant. According to the pairwise multiple comparison tests with Conover procedure and Bonferroni correction for p-values, distributions are statistically different at a level $\alpha =0.01$ in all cases for variables in panels (A–C), with the following exceptions: in panel (B), there is no significant difference between Rest and Least; in panel (C) the difference between Rest and Least is significant at a level $\alpha =0.05$.
