Exploring Optimal Cut-Offs of the MMPI-3 Substance Use Scale in Patients Seeking Metabolic and Bariatric Surgery.

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
introductionPatients seeking metabolic and bariatric surgery (MBS) complete presurgical psychological assessments to identify potential factors that may impede surgical outcomes. Presurgical psychological assessments often screen for alcohol and substance use disorders and the Minnesota Multiphasic Personality Inventory - 3 (MMPI-3) is well suited to assess for problematic alcohol or substance use. Given the potential negative health outcomes associated with problematic alcohol/substance use in patients undergoing MBS, the recommended T-score cutoff of 65T or higher may not be optimal for identifying MBS candidates at a greater likelihood of clinically elevated symptomology - especially given its face validity. The purpose of the present study was to optimize the use and accuracy of the MMPI-3 Substance Use (SUB) scale for use with patients undergoing MBS.
methodA sample of 1,257 participants from an academic medical center in the Midwest seeking MBS who produced a valid MMPI-3 protocol and had a retrospective chart review coded were included in the present study. Relative risk ratios (RRRs) were calculated to quantify the likelihood of various alcohol/substance use criteria being present at various MMPI-3 SUB scale score cut-offs.
resultsOptimal T-score cutoffs on the SUB scale ranged between 52T-58T, with 54 as the most commonly identified cutoff score that yielded the highest relative risk for problematic alcohol/substance use.
conclusionsThe recommended interpretation of the SUB scale at 54T would allow clinicians to more optimally capture those with current/past alcohol/substance problems and provide them with the appropriate pre/post-operative care if needed.
