The largest ECPR imaging study argues against its own instrument. A reassuring ratio after ECPR is the population base rate showing through, not reassurance. The authors conclude the ratio may not be sufficient after ECPR and that a multimodal approach is required.

Graded rather than threshold behaviour. Poor outcome by ratio band: 1.00-1.09, 94.6%; 1.10-1.19, 87.8%; 1.20-1.29, 78.5%; 1.30-1.39, 70.3%. Adjusted odds ratios against the 1.30-1.39 reference 10.01 (3.58-27.99), 4.83 (2.31-10.12) and 2.16 (1.02-4.55). Area under the curve 0.628 (0.59-0.66). The threshold reaching 100% specificity was 1.005, at a sensitivity of 0.1%.
