Following publication of the original article [1], we have been notified of the below corrections:
1.
On Page 1, Abstract, ‘Methods’ section, line 6: ‘intra-class coefficients’ should read ‘intra-class correlation coefficients’. This error is also present on page 8 in the ‘Abbreviations’ section.
2.
In Table 1 on page 5, within the final sentence of the notes section at the bottom of the table: the cut-off values used for the Arch Index ‘Normal: 0.21 to 0.28, high: < 0.21 and low: > 0.28’, should read ‘Normal: 0.21 to 0.26, high: < 0.21 and low: > 0.26 [23]’
