PASCAL (PFO-Associated Stroke Causal Likelihood; Kent 2021 JAMA Table 1) from a
PASCAL (PFO-Associated Stroke Causal Likelihood; Kent 2021 JAMA Table 1) from a caller-assigned RoPE total (0-10; magent does not recompute RoPE) plus large-shunt and atrial-septal-aneurysm flags. high_rope is RoPE ≥7 (not >7). high_risk_pfo is large shunt and/or ASA. probable if both, possible if exactly one, unlikely if neither. Not a closure order, not RoPE, not ESUS. Trial ages 18-60 are a limitation. magent does not read echocardiography.
