Figure 3

Allometrically scaled oxygen uptake (ml kg-0.83min-1) across [Hb] group (<10 g dl-1, 10 to 12 g dl-1, >12 g dl-1); V ˙ O 2 peak (A) and at the anaerobic threshold (AT) (B). Mean +/- SD values adjusted for weight, testing site, age, sex, revised cardiac risk index, diabetes, creatinine and operation category. P <0.0001 (ANOVA) and trend (P <0.0001) for both measures. Hb, haemoglobin concentration.
