Following publication of the original article [1], the authors identified an error in Table 1, whereby the heading row was omitted. The Marital status category is also incorrect and should read as "Married / in a durable relationship or single / widowed" instead of "Married in a durable relationship or single/widowed".

The corrected Table 1 is given below:
