Forest plot for the weighted mean difference of FVC and DLco with 95% confidence intervals in LAM patients treated with doxycycline. The weighted mean difference values of FVC and DLco were 0.02 L (95% CI: − 0.26 to 0.30) and − 1.09 ml/min/mmHg (95% CI: − 3.52 to 1.34), respectively. But the changes of them were not statistically significant, for all the P values of test for overall effect were above 0.05 (P = 0.91and P = 0.38)
