Ketamine and Esketamine for Suicidal Ideation: A Stratified Evidence Synthesis Across Intravenous, Intranasal, and Injection Routes (2016–2026)

This dataset contains structured metadata for 31 peer-reviewed studies examining ketamine and esketamine as treatments for suicidal ideation, published between 2016 and 2026. It was constructed to support a stratified evidence synthesis using a tiered, route-stratified meta-analytic methodology. The dataset underpins the companion white paper deposited on SSRN: Ketamine and Esketamine for Suicidal Ideation: A Stratified Evidence Synthesis Across Intravenous, Intranasal, and Injection Routes (2016–2026).
