It was highlighted that in the original article [1] under the section Relative growth rate (RGR) and doubling time (Dt) analysis, the equations erroneously contained some red text. In Fig.3 ref. [43] was also cited incorrectly. The correct reference in Fig. 3 is 44. The original article has been updated.
