Meta –analysis used by Krkosek et al. when calculating the 1.39 odds ratio including weights (fixed and random effects) and the I2 statistic (93%) not originally included in their letter to the Journal of Fish Diseases. Using a combined estimate base on a meta-analysis with such heterogeneity is highly questionable. The claim that the Odds Ratio is incorrect by a multiple of 30 is therefore based on flawed inference.
