*Timeframe refers to either how far back participants were asked about the occurrence of a suicide attempt (for example, in the past year), or the follow-up time.
†Prevalence rate per 100,000 person-years (i.e., the number per 100,000 persons per year) is also presented when it was either reported or it could be estimated from study follow-up time.
‡Confidence intervals (of prevalence percentages) were calculated using Stata 12.
§The 9-year cohort was extracted for the Amin 2021 study.
¶Amin 2021 study’s reported rate is 94.2 per 100,000 person-years.
#Vijayakumar 2017 study’s estimated rate is 500 per 100,000 person-years.
**Tousignant 1999 study’s estimated rate is 3450 per 100,000 person-years.
††Choi 2020 study’s estimated rate is 15,100 per 100,000 person-years.
‡‡Staehr 2006 study’s reported rate is 1032 per 100,000 person-years (for the most recent year reported, i.e., 2003).
§§Sohn 2019 study’s estimated rate is 775 per 100,000 person-years.
¶¶Median 5 months (range 1–54).
##Hermans 2017 study’s reported rate is 1400 per 100,000 person-years (95% CI, 30 to 2800).
***High income countries (HIC).
†††Absolute number of suicide attempts was not reported.
