Body composition assessment using bioelectrical impedance analysis (BIA) in a wide cohort of patients affected with mild to severe obesity.

Clinical Nutrition, 2021
BACKGROUND & AIMS Obesity is characterized by fat mass excess (FM), extra cellular water increase (ECW) and, with ageing, decrease in fat free mass (FFM).

Catalogue of bias: novelty bias

BMJ Evidence-Based Medicine, 2023
Novelty bias is the tendency for an intervention to appear better when it is new. It is also known as the ‘novel agent effects’ or ‘fading of reported effectiveness’.1 2 The mechanisms by which interventions appear better when new or new for a specific purpose are unknown and may involve other forms of bias having a more significant effect when an ...

The prognostic impact of BIA-derived fat-free mass index in patients with cancer.

Clinical Nutrition, 2021
BACKGROUND & AIMS Reduced muscle mass represents one of the top ranked phenotypic criteria for malnutrition proposed by the Global Leadership Initiative on Malnutrition. Although height-indexed fat-free mass (FFMI) thresholds have been proposed as useful

Comparative analysis of BIA, IBC, and DXA for determining body fat in American Football players.

Journal of Sports Medicine and Physical Fitness, 2021
BACKGROUND Body composition is frequently measured by sports, fitness, and healthcare professionals. Dual-Energy X-ray Absorptiometry (DXA) analysis is a validated measurement of body composition and is considered a criterion or "gold-standard ...

Catalogue of bias: observer bias

BMJ Evidence-Based Medicine, 2018
This article is part of a series featured from the Catalogue of Bias introduced in this volume ofBMJEvidence-Based Medicine that describes biases and outlines their potential impact in research studies. Observer bias is systematic discrepancy from the truth during the process of observing and recording information for a study.

Bias measuring bias

Journal of Health Services Research & Policy, 2002
The British National Health Service and other publicly funded health systems operate on the principle that health care should be provided solely on the basis of need. Yet the literature abounds with reports of bias in health care use. In order to defend such a charge, two conditions must be met.
