Correction to: Scientific Reports https://doi.org/10.1038/s41598-022-19996-7, published online 17 September 2022


The original version of this Article contained an error in the Methods, under the subheading ‘Severity index’, where the equation for the severity index \(S\) was a duplicate of the linear regression stated under the subheading ‘Statistical analysis’.


As a result, under the subheading ‘Severity index’,


$$ S \sim \beta_{{\left\{ 1 \right\}}} *a + \beta_{{\left\{ 2 \right\}}} *v + \beta_{{\left\{ 3 \right\}}} *a*v, $$

now reads:


$$S = ( P + H + D + R)/n,$$

The original Article has been corrected.
