Table 4

Age and height adjusted regression coefficients β and standard errors (SE) for the number of TB episodes and the time elapsed from last TB episode to lung function test for 26 311 miners who did not have pneumoconiosis, and loss of lung function after one episode and specific lapsed time

  • TB = tuberculosis; FEV1 = forced expiratory volume in one second; FVC = forced vital capacity.

  • 4-150 p<0.05;

  • 4-160 p<0.01;

  • 4-165 p<0.001.

  • 4-151 There were 23 710 miners who did not have TB, who were used as a comparison group in the regression model.

  • 4-152 Loss of lung function after one episode of TB and specific lapsed time from the last episode of TB.
