Forest plots. These plots depict pooled effects showing the mean difference in each hemodynamic parameter, and the heterogeneity for pre-post ketamine administration data. Mean and 95%CI are shown for systolic blood pressure (SBP) (A), diastolic blood pressure (DBP) (B), and HR (C). Random effects models were used for (A,B). A fixed effects model was used for (C) due to the low heterogeneity in the HR data.
