Family of Structurally Related Bioconjugates Yields Antibodies with Differential Selectivity against Ketamine and 6-Hydroxynorketamine.

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
The dissociative-hypnotic compound ketamine is being used in an increasingly wide range of therapeutic contexts, including anesthesia, adjunctive analgesia, treatment-resistant depression, but it also continues to be a notable substance of abuse. No specific antidotes exist for ketamine intoxication or overdose. Immunopharmacotherapy has demonstrated the ability to offer overdose protection through production of highly specific antibodies that prevent psychoactive drug penetration across the blood-brain barrier, although antiketamine antibodies have not yet been assessed or optimized for use in this approach. Moreover, generation of specific antibodies also provides an opportunity to address the role of 6-hydroxynorketamine metabolites in ketamine's rapid-acting antidepressant effect through selective restriction of metabolite access to the central nervous system. Hapten design is a critical element for tuning immune recognition of small molecules, as it affects the presentation of the target antigen and thus the quality and selectivity of the response. Here, we report the synthesis and optimization of carrier protein and conjugation conditions for an initial hapten, norketamine-N-COOH (NK-N-COOH), to optimize vaccination conditions and assess the functional consequences of such vaccination on ketamine-induced behavioral alterations occurring at dissociative-like (50 mg/kg) doses. Iterating from this initial approach, two additional haptens, ketamine-N-COOH (KET-N-COOH) and 6-hydroxynorketamine-N-COOH (HNK-N-COOH), were synthesized to target either ketamine or 6-hydroxynorketamine with greater selectivity. The ability of these haptens to generate antiketamine, antinorketamine, and anti-6-hydroxynorketamine immune responses in mice was then assessed using enzyme-linked immunosorbent assay (ELISA) and competitive surface plasmon resonance (SPR) methods. All three haptens provoked immune responses
