an overall trendp value ≤0.03
Differences in mean baseline BP across sub-populations stratified by level of OPA, LTPA, and use of anti-hypertensives showed an overall trend ( p value ≤0.03, except for those stating their OPA to be “Moderate and strenuous - with occupational lifting” and not using anti-hypertensives) of the higher the level of LTPA the lower mean BP across all levels of OPA, among those not using anti-hypertensives.
