Forest plot of the meta-analysis evaluating the Effect of CaCl2 on CS. In general, regardless of time point and the percentage of the additive, CaCl2 addition resulted in a reduction of CS. However, the subgroup meta-analysis indicated that the addition of 10% CaCl2 to MTA resulted in decreased CS on days 1 and 7 compared to MTA mixed with DW. However, this reduction was not significant on day 3. CS = compressive strength, DW = distilled water
