To the Editor:
In our article entitled "New reference values for maximal respiratory pressures in the Brazilian population", which proposed reference values for MIP and MEP and was published in a recent issue of the Brazilian Journal of Pulmonology,(1) we inadvertently erred in one of the equations, specifically in that for MIP in males.
We apologize for this error, and here we show the corrected equation:
Incorrect: Males: MIP: y = -1.24 × age + 232.37 (R2 = 60.73; RSE = 356.58; SEE = 18.88; 5th percentile = -23.38)
Correct: Males: MIP: y = -1.14 × age + 149.33 (R2 = 0.52; RSE = 422.16; SEE = 20.54; 5th percentile= -130.00)
Therefore, the full set of equations should be as below:
Males:
MIP: y = -1.14 × age + 149.33 (R2 = 0.52; RSE = 422.16; SEE = 20.54; 5th percentile= -130.00)
MEP: y = -1.26 × age + 183.31 (R2 = 48.9; RSE = 586.81; SEE = 24.22; 5th percentile = -38.95)
Females:
MIP: y = -0.46 × age + 74.25 (R2 = 24.8; RSE = 300.72; SEE = 17.20; 5th percentile = -28.83)
MEP: y = -0.68 × age + 119.35 (R2 = 35.14; RSE = 315.33; SEE = 17.76; 5th percentile = -23.24).
