* Only those variables shown to have univariate association with MPD are shown (gender, age and schooling were associated with MPD but because they were matching variables, they could not confound other associations, and so they are not shown here).

** PR adjusted for all variables in the same level and the previous levels.

¹First level. ²Second level. ³Third level. ⁴Fourth level.
