^aThe numerators and denominators of non-users do not add up in the study by Meeran et al. (2012 [8]). Numerators, 451 + 521 = 972 and not 952. Denominators, 988 + 723 = 1711 and not 1691

^bEighty-four of the 1177 questionnaires were excluded because of missing or flawed information. Therefore, only 1093 records were included
