Induced pleurodesis depending on the two techniques. a) Comparison of the sonographic score over the study. A statistically significant difference for lung sliding between both techniques is observed starting from 72 h (day 3) after the procedure. Talc poudrage achieved a higher sonographic score than talc slurry. Day 3: p=0.005; day 14: p=0.0075; day 21: p<0.0001 (Wilcoxon test). b) Comparison of the pleural thickness evaluated by chest ultrasonography over the study. No statistically significant difference in the pleural thickness was observed between the techniques except immediately after the procedure: at day 0, pleural thickness was higher after poudrage than slurry (p=0.04, paired t-test). *: p<0.05; **: p<0.01; ***: p<0.001.
