Top studies on Bias

Ranked by influential-citation count and publication year.

  1. A meta-analysis of studies using bias and precision statistics to compare cardiac output measurement techniques.

    J Clin Monit Comput1999n=25Meta-Analysis200 influential citations

    INTRODUCTION: Bias and precision statistics have succeeded regression analysis when measurement techniques are compared. However, when applied to cardiac output measurements, inconsistencies occur in reporting the results of this form of…

    Finding: The review found that the overall limits of agreement were +/-37% for studies evaluating bioimpedance and +/-65% for studies evaluating Doppler ultrasound.

  2. Individual participant data systematic review and meta-analysis of randomised controlled trials assessing adult mindfulness-based programmes for mental health promotion in non-clinical settings.

    Nature. Mental health2023n=2,371109 influential citations

    Mindfulness-based programs (MBPs) are widely used to prevent mental ill health. Evidence suggests beneficial average effects but wide variability. We aimed to confirm the effect of MBPs and to understand whether and how baseline distress,…

  3. Efficacy and safety of cAMP-biased GLP-1 receptor agonist ecnoglutide versus dulaglutide in patients with type 2 diabetes and elevated glucose concentrations on metformin monotherapy (EECOH-2): a 52-week, multicentre, open-label, non-inferiority, randomised, phase 3 trial.

    Lancet Diabetes Endocrinol2025n=623RCT4 influential citations

    <h4>Background</h4>Ecnoglutide is a novel biased GLP-1 receptor agonist that preferentially activates the cAMP pathway over β-arrestin recruitment. We aimed to assess both non-inferiority and superiority of ecnoglutide versus dulaglutide,…

  4. Impact of social prescribing on quality of life and loneliness in geriatric populations: A comprehensive meta-analysis of RCTs with implications for nursing practice.

    Geriatric nursing (New York, N.Y.)2026n=3,892

    <h4>Objective</h4>To address the fragmented evidence on the comparative efficacy of social prescribing modalities, this meta-analysis systematically evaluates the differential effects of arts-, physical-, and social-based interventions on…

  5. A Policy Analysis of Mandatory Implicit Bias Training for Perinatal Nurses.

    Nursing for women's health2026

    Mandated maternal implicit bias training (IBT) is intended to raise awareness for health care professionals to reduce maternal health disparities. The United States has high maternal morbidity and mortality, with Black non-Hispanic women…

  6. Development of a Low-Cost Spectrometer for Hemolysis Detection in Emergency Blood Gas Samples.

    The journal of applied laboratory medicine2026

    Background Hemolysis is a major cause of sample rejection in blood gas analysis. We aimed to develop a low-cost spectrometer for hemolysis detection in emergency laboratories. Methods The spectrometer was developed using a complementary…

  7. Management of Responsive Lateral Pelvic Nodes After Neoadjuvant Therapy in Rectal Cancer (RESPONDER).

    Annals of surgery2026n=844

    Objective: To determine whether lateral pelvic lymph node dissection improves oncological outcomes in patients with rectal cancer with radiologically responsive lateral pelvic nodes (LPNs) following neoadjuvant chemoradiotherapy (nCRT).…

  8. Artificial Intelligence-Based Digital Interventions for HIV Prevention in Sexual and Gender Minority Populations Globally: A Systematic Review.

    The Journal of the Association of Nurses in AIDS Care : JANAC2026n=1,729

    Sexual and gender minority populations experience high HIV incidence, and digital interventions offer prevention opportunities. Artificial intelligence (AI) enables adaptive, personalized support, yet quantitative evidence in sexual and…

  9. Corticoids Reduce Incidence of Oral Mucositis during Antineoplastic Treatment? A Systematic Review and Meta-Analysis of Randomized and Nonrandomized Clinical Trials.

    Asian Pacific journal of cancer prevention : APJCP2026n=718

    <h4>Background</h4>Oral mucositis (OM) is a serious complication of antineoplastic therapy and its clinical presentation can range from small erythematous lesions to large, debilitating ulcerative areas. This adverse effect results from…

  10. Long-Term Quality-of-Life Outcomes After Endoscopic Resection of Sinonasal and Skull Base Tumours: A Systematic Review and Meta-Analysis.

    Asian Pacific journal of cancer prevention : APJCP2026

    <h4>Introduction</h4>The present meta-analysis and systematic review aims to address the gap by examining long-term quality-of-life outcomes following endoscopic resection of sinonasal and skull base tumours. Materials and procedures: We…
