From: Variables associated with cognitive function: an exposome-wide and mendelian randomization analysis
Variables significantly associated with cognitive functions in all population and subgroups. Association between variables and cognitive functions were explored using multivariate analyses adjusting for age, sex, and APOE ε4 status. The green box represents variable positively associated with better cognitive function, while red box represents variable negatively associated with cognitive function. Highlighted variables indicate correlations with multiple cognitive tests in all population, and remain significant in all subgroups. †, fluid intelligence test; ‡, pairs matching test; §, reaction time test; ¶, prospective memory test. Edu, education; SES, socioeconomic status; Hous, household; Env, environment. NA, the variable that was not examined within specific population
