Sublingual Dexmedetomidine for Agitation Associated with Schizophrenia or Bipolar Disorder: A Post Hoc Analysis of Number Needed to Treat, Number Needed to Harm, and Likelihood to be Helped or Harmed.
Trial report in Advances in therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to 2 registered trials, which are not on this map. Cited by 2 papers.
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.

Abstract
introductionThe objective was to use the evidence-based medicine metrics of number needed to treat, number needed to harm, and likelihood to be helped or harmed to appraise the clinical efficacy and tolerability of sublingual dexmedetomidine in adults with agitation associated with schizophrenia or bipolar disorder.
methodsSublingual dexmedetomidine data for this post hoc analysis were obtained from two similarly designed, double-blind, randomized, placebo-controlled studies of adults with schizophrenia or bipolar disorder. Response to treatment was defined as a ≥ 40% reduction from baseline in the Positive and Negative Syndrome Scale-Excited Component (PEC). Tolerability was assessed by evaluating rates of adverse events.
resultsThe number needed to treat (95% confidence interval) estimate versus placebo for PEC response at 2 h post-dose was 3 (2, 3) for the sublingual dexmedetomidine 180-µg group (n = 125) and 3 (3, 4) for the 120-µg group (n = 129) in the study of patients with schizophrenia and 3 (2, 3) for the sublingual dexmedetomidine 180-µg group (n = 126) and 4 (3, 6) for the 120-µg group (n = 126) in the study of patients with bipolar disorder. Number needed to harm values versus placebo were greater than 10 for all adverse events except somnolence, where the number needed to harm (95% confidence interval) was 7 (5, 10) for all doses pooled from both studies. In all instances, likelihood to be helped or harmed values were greater than 1 for efficacy versus applicable tolerability outcomes.
conclusionsThe number needed to treat, number needed to harm, and likelihood to be helped or harmed of sublingual dexmedetomidine support a favorable benefit-risk profile in adults with acute agitation associated with schizophrenia or bipolar disorder.
