Uploaded by Ben

Correction to a prior open-access Respiratory Research article addressing an identified error in Table 4 predictive equations for pulmonary function testing in healthy Chinese children aged 4–18 years. The correction specifies that the concentration term in the predictive equations column at row 31 should use “0.825 + 0.003(age) + 0.0006(height) - 0.0014(weight)” rather than the previously published coefficients. The revised Table 4 is provided, along with licensing and publication details.

FAQs

What was corrected in the original Respiratory Research article?

An error was identified in Table 4 predictive equations, affecting the coefficients in the predictive equations column for row 31.

What is the corrected coefficient expression for the affected row in Table 4?

The corrected expression is “0.825 + 0.003(age) + 0.0006(height) - 0.0014(weight)” instead of the previously published “-0.830 + 0.003(age) + 0.001(height) - 0.001(weight)”.

How is the correction delivered in this document?

The document provides the correct Table 4 with the updated predictive equation term and includes related publication and licensing information.
