Due to an oversight during the final editing of the manuscript, there has been a shift in the references of table 1. The editorial team apologises for this mistake.
– Azhar et al. [66] should be [67]
– Memish et al. [67] should be [68]
– Hemida et al. [68] should be [69]
– Nowotny et al. [69] should be [70]
– Raj et al. [70] should be [71]
– Al Hammadi et al. [71] should be [72]
– Chu et al. [72] should be [73]
– Yusof et al. [73] should be [74]
– Al Salihi et al. [74] should be [75]
– Munyua et al. [75] should be [76]
– Li et al. [76] should be [77]
– Harrath et al. [77] should be [78]
– Kasem et al. [78] should be [79]
Additionally, table 1 cites Crameri et al [Reference Sikkema, Farag and Islam1] but should have cited Crameri et al. [Reference Crameri2], which was not present elsewhere in the paper.
