A Systematic Review of Statistical Methods Used to Test for Reliability of Medical Instruments Measuring Continuous Variables

  Objective(s): Reliability measures precision or the extent to which test results can be replicated. This is the first ever systematic review to identify statistical methods used to measure reliability of equipment measuring continuous variables. This studyalso aims to highlight the inappropriate statistical method used in the reliability analysis and its implication in the medical practice.  ...

Electro-Mechanical Testing of Conductive Materials Used in Flexible Electronics

The use of flexible electronics has increased in recent years. In order to have robust and long lasting flexible displays and sensors, the combined electro-mechanical behavior needs to be assessed. The most common method to determine electrical and mechanical behavior of conductive thin films used in flexible electronics is the fragmentation test or uniaxial tensile straining of the film and su...

Household food insecurity: a systematic review of the measuring instruments used in epidemiological studies.

OBJECTIVE To conduct a systematic review aimed at identifying and characterizing the experience-based household food security scales and to synthesize their psychometric properties. DESIGN Search in the MEDLINE, LILACS and SciELO databases, using the descriptors ('food insecurity' OR 'food security') AND ('questionnaires' OR 'scales' OR 'validity' OR 'reliability'). There was no limitation on...
