Panel plot time series for the network measures \(Q_{\mathrm{LIWC}}\) (orange) and \(f_{\mathrm{Death}}\) (green) [see Eqs. (6) and (7) respectively], and the log of the national daily deaths (blue). Each panel represents a country, and in parentheses we show the Pearson correlation coefficients between these network measures and the log of the national daily deaths. Data is smoothed with a 3-day moving average and standardised by their z-scores
