Reference Standard for Digital Infrared Thermography of the Surface Temperature of the Lower Limbs. [PDF]

Bioengineering (Basel), 2023
Digital infrared thermographic imaging (DITI) is a supplementary diagnostic technique to visualize the surface temperature of the human body. However, there is currently no reference standard for the lower limbs for accurate diagnosis.

Performance evaluation of Baermann techniques: The quest for developing a microscopy reference standard for the diagnosis of Strongyloides stercoralis

PLoS Neglected Tropical Diseases, 2021
Background Soil-transmitted helminths (STH) are common in low and middle income countries where there is lack of access to clean water and sanitation. Effective diagnosis and treatment are essential for the control of STH infections.

An objective structural and functional reference standard in glaucoma

Scientific Reports, 2021
The current lack of consensus for diagnosing glaucoma makes it difficult to develop diagnostic tests derived from deep learning (DL) algorithms. In the present study, we propose an objective definition of glaucomatous optic neuropathy (GON) using clearly

Comparative diagnostic accuracy studies with an imperfect reference standard – a comparison of correction methods

BMC Medical Research Methodology, 2021
Background Staquet et al. and Brenner both developed correction methods to estimate the sensitivity and specificity of a binary-response index test when the reference standard is imperfect and its sensitivity and specificity are known.

Quantitative Electroencephalogram Standardization: A Sex- and Age-Differentiated Normative Database

Frontiers in Neuroscience, 2021
We describe the utility of a standardized index (Z-score) in quantitative EEG (QEEG) capable of when referenced to a resting-state, sex- and age-differentiated QEEG normative database (ISB-NormDB).

Prevalence of Rotational Malalignment After Intramedullary Nailing of Tibial Shaft Fractures: Can We Reliably Use the Contralateral Uninjured Side as the Reference Standard?

Journal of Bone and Joint Surgery. American volume, 2020
BACKGROUND Intramedullary (IM) nailing is the treatment of choice for most tibial shaft fractures. However, an iatrogenic pitfall may be rotational malalignment.
