Does age affect severity of venous gas emboli on decompression from 14.7 to 4.3 psia?
Our selection of tests produced a wide range of the explanatory variables, but only age, lower body adynamia, height, and total PB time was helpful in various combinations to model the probability of DCS and VGE.
Our ecologic analysis of nearly 10,000 patients from 86 randomized trials found a superiority of the off-pump technique in patients with lower ejection fraction values, especially for the most valid outcome of mortality. As every ecologic analysis is prone to ecologic bias, a definite answer on the benefit of the off-pump technique in higher-risk patients can only be given by meta-analyses using individual patient data.
