Dear Editor,Insect Science recently published a meta-analysis that tried to test support for the slow-growth high-mortality (hereafter SG-HM) hypothesis (Chen & Chen,2018).Meta-analysis is a powerful statistical tool used to quantitatively compare and summarize multiple studies (Aqvist & Wooster,1995).However,results from a meta-analysis must be carefully interpreted when only limited sample sizes are available.Many conclusions made by Chen and Chen (2018) are based on low sample sizes and/or have small fail-safe numbers,which is problematic when making conclusions about whether the SG-HM hypothesis is supported or rejected.
