Relationship between advertisement-recruited women and experts in differences between inner urban and suburban route environments. The solid diagonal line represents the line of identity (slope = 1.0 and y-intercept = 0.0). The dotted line represents the linear regression line. The upper and lower dashed lines on either side of the linear regression line represent the 95% confidence interval (CI). The regression line (y = -0.03 [-0.80 - 0.75] + 0.84 [0.55 - 1.12] ×, [95% CI]) did not deviate significantly from the line of identity. Note that the means are sometimes minus values. The interpretation of the y-intercept could therefore be misleading. The 95% CI for the slope therefore gives a better picture, showing that the linear regression line did not deviate significantly from the line of identity. Pearson's correlation was 0.85.
