Fig. 3From: Role of ICU-acquired weakness on extubation outcome among patients at high risk of reintubationBox plots showing median MRC sum-score (25th–75th percentiles) according to cough strength considered as absent, weak or ineffective, moderate, effective, and very effective. MRC sum-score and cough strength were weakly but significantly correlated (rho 0.28; p < .001 using Spearman’s test)Back to article page
