Although my centre develops the statistical software the whole Cochrane Collaboration uses for its systematic reviews and meta-analyses (Review Manager), I have often used Comprehensive Meta-Analysis for my own research projects, as it is easy to import data from Excel, to use effect modifiers, and also because it allows meta-regression and produces bubble graphs that are easy to work with in Word or PowerPoint.
