Relation between the changes in Pimax (ΔPimax) after 3 months and the changes in daily duration of NPPV (ΔNPPV) at home in the RMT group (●) and control group (⎔). There was a significant correlation between both measures when taken over both groups (ρ=−.61, P=.002). The line indicates the relationship derived from orthogonal linear regression.
