Table 2: Summary of the observed effects of the outlined 14 options to
treat missing standard deviations (SDs) and/or sample sizes (SSs) on the
estimated grand means and confidence intervals in comparison to the
results from fully informed weighted meta-analyses in four simulated
data sets with different patterns of missingness and correlation
structures (MCAR – m issing c ompletely a tr andom, MAR – m issing a t r andom,
MNAR – m issing n ot a t r andom and
corMCAR – SDs/SSs are cor related to effect sizes andm issing c ompletely a t r andom).
