Meta-analysis limitations
Research gap analysis derived from 2 medicine papers in our local library.
The gap
The heterogeneity in study designs and outcome measurements across multiple systematic reviews precludes quantitative meta-analytic synthesis.
Consensus across the literature
Papers collectively establish that standardization is needed for diagnostic criteria, patient populations, and study protocols to enable future meta-analyses.
Research trend
Emerging — attention growing, methods still coalescing.
