Verifications by Passing–Bablok regression analysis for fixed error and proportional error against the respirometry criterion in streaked shearwaters

^*Subjects in three groups were exposed with different experimental conditions: at rest on the ground for 24 h (Group A) or for 48 h (Group B), and at rest on the water for 24 h (Group C).

^**Values are the 95% CI for fixed error (intercept ≠ 0) and proportional error (slope ≠ 1) for each method against the respirometry criterion.

^***Passing–Bablok regression analysis gave false values on 95% CI for intercept and slope and could not evaluate the fix and proportional error.
