Meta-analyses typically calculate effect sizes across studies and then combine them to form an overall effect size. This allows for more precise conclusions to be drawn compared to analyzing the individual studies separately. Sample size, level of significance, and confidence intervals can also be important factors, but they are typically used in conjunction with effect sizes rather than as the primary statistic for forming conclusions.
