Efficacy and safety of aripiprazole once-monthly in obese and nonobese patients with schizophrenia: a post hoc analysis.
Article in Neuropsychiatric disease and treatment, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00706654 (A 38-week, Multicenter, Randomized, Double-blind, Active-controlled Study to Evaluate the Efficacy, Safety, and Tolerability of an Intramuscular Depot Formulation of Aripiprazole), which is not on this map.

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.

Abstract
purposeTo assess the efficacy and safety of aripiprazole once-monthly 400 mg (AOM 400), an extended-release injectable suspension of aripiprazole, in obese and nonobese patients. PATIENTS AND
methodsThis post hoc analysis of a 38-week randomized, double-blind, active-controlled, noninferiority study (NCT00706654) compared the clinical profile of AOM 400 in obese (body mass index [BMI] ≥30 kg/m(2)) and nonobese (BMI <30 kg/m(2)) patients with schizophrenia for ≥3 years. Patients were randomized 2:2:1 to AOM 400, oral aripiprazole 10-30 mg/d, or aripiprazole once-monthly 50 mg (AOM 50 mg) (subtherapeutic dose). Within obese and nonobese patient subgroups, treatment-group differences in Kaplan-Meier estimated relapse rates at week 26 (z-test) and in observed rates of impending relapse through week 38 (chi-square test) were analyzed. Treatment-emergent adverse events (TEAEs) (>10% in any treatment group) were summarized.
resultsAt baseline of the randomized phase, obesity rates were similar among patients randomized to AOM 400 (n=95/265, 36%), oral aripiprazole (n=95/266, 36%), and AOM 50 mg (n=43/131, 33%). In both obese and nonobese patients, relapse rates through week 38 for patients randomized to AOM 400 (obese, 7.4%; nonobese, 8.8%) were similar to those in patients on oral aripiprazole (obese, 8.4%; nonobese, 7.6%), whereas relapse rates were significantly lower with AOM 400 versus AOM 50 mg (obese, 27.9% [P=0.0012]; nonobese, 19.3% [P=0.0153]). The most common TEAEs with AOM 400 in obese and nonobese patients were insomnia (12.6% and 11.2%), headache (12.6% and 8.2%), injection site pain (11.6% and 5.3%), akathisia (10.5% and 10.6%), upper respiratory tract infection (10.5% and 4.7%), weight increase (10.5% and 8.2%), and weight decrease (6.3% and 11.8%). Within the AOM 400 group, 7.6% of patients who were nonobese at baseline became obese, and 17.9% of obese patients became nonobese during randomized treatment.
conclusionThe clinical profile of AOM 400 was similar in obese and nonobese patients.
