The Ketamine Trial for Acute Suicidality (KETA): Study Protocol of a Double-Blind Randomized Placebo-Controlled Superiority Trial on Intranasal Racemic Ketamine Compared to the Active Placebo Intranasal Midazolam as Treatment for Acute Suicidality.
Article in International journal of methods in psychiatric research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSuicidality is a transdiagnostic entity in patients with and without psychiatric disorders. Ketamine is a novel treatment for treatment-resistant depression with favorable effects on related suicidality in this population. Little is known about the effects of ketamine on suicidality as a distinct phenomenon.
objectiveTo assess whether a dose of 75 mg intranasal (IN) ketamine reduces acute suicidality relative to a 4 mg intranasal dose of the active placebo midazolam, 180 min after administration. METHODS/
designA double-blind randomized placebo-controlled trial (N = 100) will assess the efficacy of fixed-dose IN racemic ketamine in patients presenting with acute suicidality, regardless of psychiatric diagnosis. Participants receive a single IN dose of either racemic ketamine (75 mg) or midazolam (4 mg) along with treatment as usual. The primary outcome is the reduction in suicidal ideation as measured by the Beck Scale for Suicide Ideation (BSSI) at 180 min. Secondary outcomes include depression severity with the Montgomery Åsberg Depression Rating Scale (MADRS) and tolerability with the Systematic Assessment for Treatment Emerging Effects (SAFTEE) as well as blood-based and neuroimaging markers. DISCUSSION: This study design considers key aspects such as patient selection, ketamine formulation, clinical management, and the follow-up time points. Potential risks, limitations, and future considerations are additionally discussed.
