In addition, while keeping all other factors fixed, the occurrence of ageusia during acute COVID-19 was also found to be a relevant predictor of the MoCA-B outcome, although the evidence supporting such an association remained marginally significant ( Table 4 ) (Wald test: estimate = −0.939, SE = 0.489, Z = −1.920, p = 0.054).
In addition, while controlling for the other factors, participants’ income was also likely to influence the performance on MoCA-B test, although the evidence provided by the sample to support such an association was insufficient to overcome the significance level, hence remaining as a statistical trend ( Table 3 ) (Wald test: p = 0.070 and p = 0.054, respectively for the contrasts between R$10 k–R$15 k and R$15 k–R$23 k, both related to R$1 k–R$1.6 k).
