From: Estimation bias and agreement limits between two common self-report methods of habitual sleep duration in epidemiological surveys

Figure 4

HSD estimation bias as a function of Sleep Quality by (a) Method-MCTQwork versus (b) Method-MCTQfree. HSD estimation bias values are smaller (closer to zero line) in the Method-MCTQwork as compared with the Method-MCTQfree in all Sleep Quality groups. Green areas around the means—the 95% limits of agreement (± 1.96 SDs). Note that the Method-MCTQwork narrower agreement ranges in all Sleep Quality groups as compared to the Method-MCTQfree.
