Table 4:

Cox proportional hazard model assessing the Hazard Ratio of a reduction in small venous blood volume with 30- and 90-day mortality after adjusting for age, sex, lung volume, small arterial blood volume, abnormal RV:LV ratio and presence of cancer. Hazard's ratios reported here are per 1 standard deviation (17.84ml) decrease in small venous volume
