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).
