Clinical characteristics of over-the-counter (OTC) drug abusers in psychiatric practice in Japan: Comparison of single and multiple OTC product abusers.
Article in Neuropsychopharmacology reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo examine the clinical characteristics of over-the-counter (OTC) drug abusers in psychiatric practice in Japan.
methodWe examined the attributes, ICD-10 subcategory, and comorbid mental disorders of patients who mainly abuse OTC products and compared the clinical characteristics of single product and multiple products abusers, using the database of the "2022 Nationwide Mental Hospital Survey of Drug-related Disorders."
resultsAmong the 2468 subjects included in this survey, 273 (11.1%) used OTC products as main drugs. Of these, 209 (78.3%) and 58 (21.7%) were classified into the single product group and the multiple products group, respectively. Six were excluded for unknown ingredients. By comparing these groups, we found that many of the multiple products group consisted of young women who were recently treated for drug problems. Many subjects in the group also had a short treatment period. No differences were observed between the groups regarding the ICD-10 F1 subcategory, but many subjects in the multiple products group fulfilled the criteria of F6 "disorders of adult personality and behavior."
conclusionOTC products are easily accessible drugs of abuse for young women in Japan. The results of this study indicate the necessity to reconsider the educational approach for preventing drug abuse, which has focused on illicit drugs. The study also indicates that some OTC products, which contain ingredients banned overseas due to their harmful effects, are still sold in Japan and that abusers for those products exist. Measures by the government are considered urgently needed.
