Psychological Profiles and 12-Month Weight Outcomes of Women Evaluated for Reoperative Bariatric Surgery.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe use of psychological screening instruments prior to bariatric surgery has been well established. However, there is currently no specific literature on psychological screening of candidates for reoperative bariatric surgery.
methodsThis study evaluated archival data for 40 women who were candidates for reoperative bariatric surgery and completed the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF). Profile analysis examined differences between patient groups who did and did not undergo reoperative surgery. MMPI-2-RF profiles for reoperative patients then were compared to previous samples of preoperative and postoperative patients. Hierarchical linear modeling was used to predict BMI following reoperative surgery over a 12-month period based on MMPI-2-RF scales while controlling for age and initial BMI.
resultsProfile analysis results showed no significant differences on MMPI-2-RF scale scores between reoperative candidates who did and did not undergo a second surgery. With some minor differences attributed to minimization of symptoms, there were no systematic differences in MMPI-2-RF scale scores for reoperative surgery patients compared to preoperative and postoperative patient groups. BMI outcomes over a 12-month period showed that age and initial BMI were significantly better predictors than MMPI-2-RF scores.
conclusionsAdministration of MMPI-2-RF for reoperative bariatric surgery patients likely is equivalent to its typical use in preoperative screening. Only the MMPI-2-RF Disconstraint scale showed any relationship to BMI outcomes over time following reoperative surgery.
