From: Particulate matter exposure and health impacts of urban cyclists: a randomized crossover study

RHI 0.066 −0.22, 0.35 −0.051 −0.25, 0.15
FEV1 (mL) −4.1 −53, 45 −32 −66, 3.0
FVC (mL) −63 − 145, 19 −41 −102, 19
CRP (μg/dL) 8.7 −14, 32 2.2 −14, 19
IL-6 (pg/mL) 0.78 −0.45, 2.0 0.64 −0.20, 1.5
8-OHdG (ng/mL) 0.027 −0.013, 0.067 0.010 −0.019, 0.039
  1. ß-coefficient values are presented for an interquartile range change in PNC (7637 pt/cm³) or PM2.5 (4.7 μg/m3) exposure
