Age-specific impacts of body weight (BW) on PEF and FEF<sub>50</sub> estimated for three different age groups of male and female participants. OmoriHisamitsu OnoueAyumi KatohTakahiko OgataYasuhiro KawashimaHidetoshi MiyaoNaoki TsujiTakao AoshibaKazutetsu NagaiAtsushi YamaguchiKazuhiro 2014 <p>(A): Partial regression coefficients of Ln(BW) for the reference means of Ln(PEF) in young-, middle-, and advanced-age groups of both genders. Partial regression coefficients of Ln(BW) for Ln(PEF) are defined as ΔLn(PEF)/ΔLn(BW). (B): Partial regression coefficients of Ln(BW) for Ln(FEF<sub>50</sub>) are defined as ΔLn(FEF<sub>50</sub>)/ΔLn(BW).</p>
