The circles and error bars are mean and standard deviation. *mean difference (95% CI) 5.0 (1.3–8.8) kPa, P = 0.008; †4.4 (1.2–7.6) kPa, P = 0.007; ‡5.0 (1.3–8.8) kPa, P = 0.008; §5.3 (1.3–9.2) kPa, P = 0.008; 4.9 (-8.8 to -1.2) kPa, P = 0.010; ║median (interquartile range) 5.1% (2.5–10.4%) vs 7.7% (5.0–11.8%), P = 0.008.
