  • * | y-intercept at x = −100% |.

  • Value for first tertile was significantly different from that for other tertiles (P ≤ 0.01).

  • Value for first tertile was significantly different from that for other tertiles (P ≤ 0.02).

  • § 95% confidence interval for third-tertile correlation coefficient (95% CI, 0.90–0.99) did not include first- and second-tertile correlation coefficients.
