Fig. 1: Factors associated with post-COVID cognitive deficits.

Association between baseline characteristics and MoCA at 6 months (measuring objective cognitive deficits, lower indicate more deficits) and C-PSQ at 6 months (measuring subjective cognitive deficits, higher means more deficits). Age was z-transformed in this analysis which means that the coefficient corresponds to a difference in MoCA/C-PSQ corresponding to a difference of 1 × s.d. in age. Only one level of education and one income level are presented (with no education and income <£19,000 being taken as references respectively). The same graphs with all education and income levels, as well as ethnicity, are presented in Supplementary Figs. 1 and 2. n = 1,837 individual participants. Dots indicate point estimates and horizontal lines indicate 95% CI. P values were estimated as part of a generalized linear model and are two-sided and not adjusted for multiple comparisons: ^oP < 0.1, *P < 0.05, **P < 0.01, ***P < 0.001.
