After SMV , onset times of the PD ( p = @ ) , BB ( p = @ ) and ECR ( p = @ ) in the EG were less anticipated than at baseline ; the modulation ratio increased in AD ( p = @ ) and BB ( p = @ ) ; co-contractions decreased in the pairs BB/TB ( p = @ ) , PD/BB ( p = @ ) and AD/BB ( p = @ ) ; and the degree of contraction decreased in BB ( p = @ ) .
