Impact of chronic alteration in the circadian rhythm on lung
function
Figure 2 showed that policemen working in an irregular and alternated
scale presented impaired lung function, as denoted by reduced FVC (%
predicted) (Figure 2A; p<0.0053) and FEV1 (% predicted)
(Figure 2B; p<0.043). However, other parameters of lung
function, such as FEV1/FVC (% predicted) (Figure 2C;
p>0.05), PEF (% predicted) (Figure 2D;
p>0.05), MEF25% (% predicted) (Figure 2E;
p>0.05), MEF50% (% predicted) (Figure 2F;
p>0.05), MEF75% (% predicted) (Figure 2G;
p>0.05) and IN VC (% predicted) (Figure 2H;
p>0.05) present no differences when compared to civil men.
