Appetite measures during ketamine administration in treatment-resistant mood disorders: a naturalistic study.
Article in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study evaluated the acute and short-term effects of repeated ketamine treatment on appetite in adult inpatients with treatment-resistant mood disorders, including major depressive disorder and bipolar disorder. Appetite, hunger, and desire to eat were assessed using the Visual Analog Scales (VAS) and the Simplified Nutritional Appetite Questionnaire (SNAQ) at baseline and at multiple time points up to 7 days following ketamine administration. No significant changes were observed over the course of treatment, and results were consistent across diagnostic groups and body mass index (BMI) categories. No increased risk of appetite-related undernutrition or clinically relevant weight loss was identified. These findings do not suggest a substantial short-term impact of ketamine on appetite regulation or body weight and are consistent with a favorable metabolic safety profile, supporting its clinical use in patients with treatment-resistant depression (TRD) and treatment-resistant bipolar disorder (TRBD).
