Tusi use among the New York City nightclub-attending population.

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
BACKGROUND AND
aims'Tusi', also known as 'tusibí' or 'pink cocaine', is a drug concoction which previously emerged in Latin America and Europe and has recently acquired popularity in the United States (US). Consumers are often unaware that Tusi contains a mixture of ketamine and other drugs, and the concoction can be confused with 2C/2C-B (ring-substituted phenethylamines/4-bromo-2,5-dimethoxyphenethylamine) or cocaine. This study aimed to estimate the prevalence and correlates of past-year Tusi use in the electronic dance music (EDM) nightclub-attending population in New York City (NYC), US. DESIGN AND
settingThis cross-sectional study included surveys and optional saliva testing of adults entering randomly selected EDM events in NYC in 2024.
participantsAdults aged ≥18 years entering EDM events at nightclubs (n = 1465). MEASUREMENTS: Exposures were demographic characteristics and past-year use of other drugs. The primary outcome was self-reported past-year use of Tusi, and in a subsample, biologically confirmed exposure to various drugs determined by saliva testing.
findingsBased on self-report, an estimated 2.7% [95% confidence interval (CI) = 1.9-3.9] of adults in the NYC EDM nightclub-attending population have used Tusi in the past year. Compared with white individuals, Hispanic individuals were at higher odds for use [adjusted odds ratio (aOR) = 5.10, 95% CI = 1.96-13.25]. Compared with those who did not use, those who used ecstasy/3,4-Methylenedioxymethamphetamine (MDMA) (aOR = 6.59, 95% CI = 1.60-27.16), ketamine (aOR = 3.44, 95% CI = 1.18-10.08) and/or 2C series (aOR = 14.82, 95% CI = 4.77-46.04) in the past year were at higher odds for use. Compared with those not reporting Tusi use, those reporting past-year use were more likely to have saliva test positive for cocaine, ketamine, MDMA, methamphetamine and/or synthetic cathinones (Ps < 0.001). They were also more likely to test positive for cocaine, ketamine or methamphetamine after not reporting past-year use (Ps < 0.01).
conclusionsAn estimated 2.7% of electronic dance music-nightclub attending adults in New York City appear to have used Tusi in the past year, with higher use among Hispanic individuals and people exposed (sometimes unintentionally) to other drugs.
