Association of General Personality Traits with Outcomes in Total Hip Arthroplasty: A Multicenter, Cross-Sectional, Prospective Trial.
Article in Clinics in orthopedic surgery, 2026. 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
Background: The influence of psychological traits such as depression on postoperative outcomes after total hip arthroplasty (THA) is known, but data on general personality traits, such as optimism and pessimism, remain scarce. Understanding the impact of optimism and pessimism on postoperative outcomes in THA patients could provide valuable insights for preoperative patient assessments and postoperative care strategies. We hypothesized that patients with higher levels of optimism would demonstrate superior functional outcomes and that the opposite applies to pessimistic patients. Methods: A prospective, multicenter, cross-sectoral study assessed the association of personality traits with preoperative and 3, 6, and 12-month postoperative functional scores (12-item Hip Disability and Osteoarthritis Outcome Score [HOOS-12]). Optimism and pessimism were measured preoperatively via the revised Life Orientation Test (LOT-R). Linear regression models were fitted, and coefficients of determination (R Results: Eight hundred forty-six patients were analyzed. Optimism was significantly associated with HOOS-12 scores over the first postoperative year, whereas pessimism was significantly associated for 6- and 12-month follow-up (preoperative: optimistic Conclusions: Optimism and pessimism are opposing and significantly associated with postoperative outcomes after THA, although not reaching the minimal clinically important change of the HOOS-12 score. If patients scheduled for THA seem prone to pessimistic behavior, further screening of the patient's personality traits and other risk factors should be conducted. The outcomes of these patients could be improved through psychoeducation or cognitive behavioral interventions.
