did not reach statistical significanceno p-value reported

Risk rose steeply as PP fell below 50 mmHg, plateaued thereafter for all-cause mortality (inverse J-shape), and trended upward again for cardiac death when PP exceeded approximately 80 mmHg (U-shape), although the latter did not reach statistical significance ( Figure 3 ).
