Forest plot of the meta-analysis evaluating the effect of CaCl2 on cytotoxicity. The result of the subgroup meta-analysis indicated that the addition of 5% CaCl2 did not increase cell cytotoxicity of MTA on days 1, 3, and 7. However, the addition of 10% CaCl2 resulted in a significant reduction of cell viability on days 1 to 7 compared to MTA mixed with DW. CV = cell viability
