متن کاملA Meta-analysis of Randomized Controlled Trials
Design: A systematic search for randomized controlled trials comparing total tonsillectomies performed using vessel sealing systems (VSS), Harmonic Scalpel (HS), or radiofrequency ablation (ie, Coblation) with the conventional technique of cold steel and/or electrocautery dissection (CS/EC). Estimation of odds ratios and 95% confidence intervals (CIs), weighted mean differences (WMD), or standa...
