From: Conventional laboratory housing increases morbidity and mortality in research rodents: results of a meta-analysis

Fig. 9

Random-effects meta-analysis of housing effects showing overall ratio of means (ROM) and 95% confidence intervals of median survival. Subgroups are based on if animals died spontaneously or after disease induction. Blue diamond = SMD estimate (with the width reflecting the 95% CI), location of black squares indicates study ratio of means and size indicates the weight of the study in the meta-analysis. CH = conventional housing, EH = ‘enriched’ housing, RE = random effects. I2 and Q statistic are tests of heterogeneity. Results of the model testing whether ROMs are significantly different from one: n = 15, z = − 7.04, p < 0.0001
