1 · What the graph read from it

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.

2 · The registry

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

Background: Treatment-resistant depression (TRD) remains a challenge, but intravenous racemic ketamine offers rapid antidepressant effects. Reliable biomarkers are needed. In this study, we examined kynurenine pathway metabolites and inflammatory cytokines as predictors of ketamine response. Methods: The Bio-K study was a multicenter, open-label trial of 74 patients with TRD who received 3 ketamine infusions over 11 days. Remission (Montgomery-Åsberg Depression Rating Scale [MADRS] score ≤9) was assessed 24 hours post infusion 3, with a subset of study participants continuing weekly infusions. Plasma biomarkers (9 kynurenines, 14 cytokines) were measured at baseline and post infusion. Mixed-effects models and logistic regression analyses were used, adjusting for sex, age, body mass index, benzodiazepine use, and baseline MADRS scores. Second-generation Results: Of the 74 participants, 52% ( Conclusions: Elevated AA levels and AA-based biomarker ratios predicted ketamine remission in patients with TRD, supporting biomarker-driven personalized treatment. These findings highlight immunometabolic mechanisms in ketamine response.
