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 and hypothesisAntipsychotic use in severe mental illnesses (SMI) is associated with metabolic dysregulation, including antipsychotic-induced weight gain (AIWG), type 2 diabetes (T2D), and dyslipidemia. In the case of non-response to metformin which is currently recommended for AIWG mitigation, no clear alternatives exist. Semaglutide, a weekly injectable glucagon like peptide-1 receptor agonist, represents a promising option. However, effectiveness and safety data in SMI are lacking. With initiation of semaglutide, we hypothesized weight loss, improvements in metabolic indices, and good tolerability. STUDY

designA retrospective chart review was conducted for inpatients receiving antipsychotics, initiated on once-weekly subcutaneous semaglutide between January 4, 2018 and March 31, 2024 at the Centre for Addiction and Mental Health in Toronto, Canada, that analyzed weight loss, metabolic parameters, and side effects. STUDY

results47 individuals with SMI were included: 59.6% males, mean age of 43 ± 13.2 years, 83% had dysglycemia, and 66% had T2D at baseline. The maximum dose of semaglutide in this cohort was 2 mg/week. There was a mean weight loss of 3.15 ± 0.77 kg (n = 47), 7.27 ± 0.97 kg (n = 24), 9.33 ± 1.16 kg (n = 15), and 12.25 ± 1.32 kg (n = 11) at 3, 6, 9, and 12 months, respectively (P < .001). Individuals without T2D experienced greater weight loss versus those with T2D (P = .022). Additionally, significant decreases were noted in body mass index and HbA1c (P < .001), alongside improvements in lipid parameters; most common side effects were gastrointestinal in nature but did not result in semaglutide discontinuation.

conclusionThis retrospective chart review of inpatients with SMI supports efficacy and safety of semaglutide up to a year of follow-up, warranting future adequately powered randomized controlled trials.
