Based on the results, the prevalence of suicide ideation and attempt among all studies were equal to 13% (95% confidence interval = 0.11-0.15, I2 = 99.7%, P = 0.00) and 1% (95% confidence interval = 0.00-0.01, I2 = 95.5%, P = 0.00), respectively. Based on the results, the prevalence of suicide attempt and ideation is possible during the COVID-19 pandemic.
