However, only a minority of individuals who die by suicide leave a note, raising the question of whether note\u00a0writers (NW) are representative of the broader population of suicide decedents. This systematic review aimed to synthesize the available evidence on differences between NW and non\u2010note writers (NNW) across sociodemographic, clinical, psychosocial, and suicide\u2010related variables. A systematic search was conducted in PubMed and ProQuest databases up to June 22, 2026, following PRISMA guidelines. Studies were included if they compared NW and NNW on at least one variable, or investigated predictors of note\u2010leaving. Thirty\u2010three studies met the inclusion criteria. Evidence was heterogeneous and suggested that NW cannot be clearly distinguished from NNW based on sociodemographic and clinical variables. Concerning suicide\u2010related variables, the method of suicide was the most consistently different between NW and NNW; in particular, the most frequent methods of suicide in NW, compared to NNW, were non\u2010violent methods like poisoning\/overdose and gas inhalation. Rather than solely reflecting a distinct psychological profile, suicide note\u2010leaving may also be influenced by the circumstances surrounding the suicidal act. One possible, although untested, explanation is that leaving a note requires a degree of cognitive and emotional organization that may be less compatible with highly disorganized or impulsive suicidal states.<\/jats:p>","DOI":"10.1002\/pcn5.70414","type":"journal-article","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T11:32:38Z","timestamp":1790767958000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Who leaves a suicide note?
