Fig. 2.

A Histological Lung Injury Score from recipient sheep treated with either no ventilation (NOVENT ■) or open-lung ventilation (OPENVENT ●) during cardiopulmonary bypass. Data were clustered into lobes and shown as mean ± SEM with n = 8 for both groups. The effect size and p-values of the mixed analysis are reported from top to bottom of factor ventilatory strategy, lobe and interaction between these two factors. LUL left upper lobe, RUL right upper lobe, RML right middle lobe, RLL right lower lobe and LLL left lower lobe
