Figure 4

Changes in activated partial thromboplastin time with nebulised heparin dosage. Upper: Change in the activated partial thromboplastin time (APTT) over time. The last dose of heparin was given at 36 hours for all groups except the 400,000 U/day group, in which it was administered at 42 hours (mean levels; P = 0.06, comparison of 46-hour and 58-hour timepoints in the 400,000 U/day group). Lower: APTT at baseline and following the final dose of nebulised heparin (P = 0.09, analysis of variance comparison by dose, mean and standard deviation).
