Fig. 2From: Capillary lactate concentration on admission of normotensive trauma patients: a prospective studyAgreement between the capillary lactate measurement device and serum blood lactate concentration via the Bland & Altman representation (n = 60 patients). Central dash-line represents the linear bias between the two methods. Upper and lower black lines represent the 95 % prediction limits for the blood lactate given the value by the capillary methodBack to article page
