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

backgroundSchizophrenia is a complex psychiatric disorder characterized by positive, negative, and cognitive symptoms. KarXT, a novel combination of xanomeline and trospium, offers potential therapeutic benefits for schizophrenia treatment by targeting muscarinic receptors and avoiding dopamine receptor blockade. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of KarXT.

methodsPubMed, Scopus, Web of Science, and Cochrane databases were systematically searched for relevant randomized controlled trials (RCTs) up to October 2024. Studies involving adult patients with schizophrenia treated with KarXT were included. Furthermore, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was used to assess evidence quality, and the risk of bias was evaluated using the Cochrane Risk of Bias 2.0 tool.

resultsFour studies with 690 participants were included. KarXT significantly reduced Positive and Negative Syndrome Scale (PANSS) total scores compared to placebo (mean difference (MD): -13.77, 95% confidence interval (CI) [-22.33 to -5.20], P-value = 0.002), with significant improvements in positive and negative subscale scores. It significantly increased the incidence of achieving ≥ 30% PANSS score reduction (risk ratio: 2.15, 95% CI [1.64 to 2.84], P < 0.00001). Moreover, KarXT demonstrated a favorable safety profile, with side effects such as nausea and constipation being mild and transient. Notably, it was not significantly associated with weight gain or extrapyramidal symptoms, which are common with traditional antipsychotics.

conclusionsKarXT's distinct mechanism and tolerability highlight its potential to address unmet needs in schizophrenia treatment. Future studies should explore its long-term efficacy, delayed adverse effects, and comparative effectiveness against existing therapies. CLINICAL TRIAL NUMBER: Not applicable.
