effect_sizes: effect sizes (e.g., standardized mean differences)
effect_size_variances: within-study variances
ci: width of the confidence interval (default = 0.95)
one_tailed: logical. If one_tailed = FALSE, a two-tailed p-value will be calculated. If one_tailed = TRUE, a one-tailed p-value will be calculated (default = FALSE)
random_vs_fixed: If random_vs_fixed = "random", the summary effect will be calculated under the random-effects model (default = "random").
