Efficacy of tetrastarch compared to albumin, gelatin or crystalloids as judged by total volume infusion. Units of total combined volume of colloids and crystalloids were expressed in millilitres (ml), except for Hanart et al. [43] and Van der Linden et al. [38],[52], where units were expressed as millilitres per kilogram body weight (ml/kg). (A) Albumin. (B) Gelatin. (C) Crystalloid. The standardised mean difference (Std. mean difference) of the mean for the hydroxyethyl starch group minus the mean for the albumin group was used as effect size. Fixed-effects models were applied to calculate a common effect estimate using the inverse variance method (IV). SD, standard deviation; CI, confidence interval.
