*

Detailed information on each trend, both overall and exclusive of MVMM is presented in eTable 3

a

Among adults ages ≥ 20 years.

b

A ‘decrease’ corresponds to a ratio<1 and p-trend<0.05, an ‘increase’ represents a ratio>1 and p-trend<0.05, and ‘stable’ represents a p-trend≥0.05.

c

Data are weighted to be nationally representative.

- Dash represents suppressed data due to unstable data, if the relative standard error exceeds 30%, consistent with NHANES reporting guidelines.40
