Table 4 Multiple linear regression model for percentage cross-shift change in PEF (ΔPEF%) among 50 male cement workers

From: Cement dust exposure and acute lung function: A cross shift study

  Covariates B SE p 95%CI
ΔPEF% Constant 5.46 2.19 0.016 1.05, 9.87
  Years in high-exposed section -0.80 0.37 0.036 -1.55, -0.05
  Current smoking (0/1) -6.60 4.45 0.144 -15.53, 2.33
  Log-"total" dust (mg/m3) -1.62 0.73 0.032 -3.09, -0.15
  1. ΔPEF% = [(postshift PEF - preshift PEF)/preshift PEF] times 100. B: regression coefficient. SE: standard error of regression coefficient. 95% CI: 95% confidence interval.
