Fig. 4

Scatter diagram of clinical factors associated with MASPs. a Scatter diagram of BMI and MASP when the LCA was open. The black dots represent the corresponding BMI and MASP when the LCA was open, and the red line represents the linear fitting (r = 0.460). b, c Scatter diagram of BMI and MASP when the LCA was open and when it was clamped. The black dots represent the corresponding SP and MASP, and the red line represents the linear fitting (r = 0.376 and 0.302). d Scatter diagram of the LCA diameter and the amplitude of MASP change after the LCA was clamped. The black dots represent the corresponding LCA diameter and the amplitude of MASP change, and the red line represents the linear fitting (r = 0.891)
