1. Ejection fraction preoperatively and at follow-up in conventional (C) and no-touch (NT) groups.
Ejection fraction preoperatively and at follow-up in conventional (C) and no-touch (NT) groups. Statistical significance for difference between groups at 16-year follow-up, adjusted for prevalues, is shown by p1. Lines indicate gradient for ejection fraction from preoperation to 16-year follow-up and p2 shows statistical significance between groups with respect to gradient. Two hundred and eight observations on ejection fraction for 83 patients, number of observations for each assessment is shown in the figure.
