Validation of the alcohol, smoking and substance involvement screening test (ASSIST) for identifying methamphetamine use among people on methadone maintenance treatment in Vietnam.

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
aimsIdentifying those who use methamphetamine or are at high risk of using methamphetamine is essential so that early, appropriate intervention can be made. This study evaluated the use of the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) for identifying methamphetamine use among people on methadone maintenance treatment (MMT) in Vietnam.
methodsFrom June 2021 to May 2023, all people on MMT at 15 methadone clinics in Hanoi and Ho Chi Minh City, Vietnam, were invited to participate in this study. Participants underwent a face-to-face interview to complete the 8-item ASSIST. Participants also had a urine drug test (UDT) for methamphetamine use. Discriminant properties of the ASSIST were evaluated using UDT as the reference.
resultsAmong 6709 participants, 10.7% (n = 717) tested positive for methamphetamine use via UDT. The ASSIST demonstrated robust discriminant abilities to identify those who used methamphetamine [area under the curve (AUC) = 0.872; 95% confidence interval (CI) = 0.856-0.887]. At the commonly used cutoff of 4, the ASSIST had a sensitivity of 83.8% and a specificity of 82.0%. At this cutoff, 82.2% of the ASSIST results aligned with UDT outcomes (kappa coefficient = 0.41, P < 0.001) and the ASSIST identified a prevalence of 25.0%. At higher cutoffs, the sensitivity of the ASSIST decreased but both the specificity and the agreement with the UDT results increased.
conclusionsThe Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) appears to be reliable and valid in identifying methamphetamine use among people on methadone treatment in Vietnam. Cutoff adjustments may help to reduce false positive rates.
