Table 2. Statistics for two sites and two years of powdery mildew infection.

Regression coefficients (intercept and slope of regression lines in figures), slope probability (p), adjusted r², 95% confidence intervals, standardised slope coefficient (SSC, see Eq 3), 95% confidence interval of SSC assessed with Delta method [37], and Pearson correlation coefficient (r). Note: r and the slope have equal probabilities.
