Studies used various inclusion criteria and assessment tools. One cannot infer general PTSD prevalence from a single study. Pooling data requires careful data processing with content expertise. It is an important step towards generalizable prediction models for PTSD; Trauma; United States--US; PTSD; TEPT; pooled analysis; predicción; data harmonization; análisis combinado; armonización de datos; prediction; longitudinal
