Table 3.

Analysis of neuropathic pain data using a mixed effects model, with 19% missingness in sample variances. TE denotes treatment effect and SE denotes standard error. NM is no missingness, MI is multiple imputation using gamma meta-regression, ME is mean imputation, SGR is single imputation using gamma meta-regression, SLM is single imputation using linear regression based on the log-variance, and CC is complete case analysis.
