In order for authors of systematic reviews to address missing data in randomized controlled trials (RCTs), they need to first identify the number of trial participants with missing data.

Missing ordinal data are common in studies using structural equation modeling (SEM). Although several methods for dealing with missing ordinal data have been available, these methods often have not be...
Missing data result in less precise and possibly biased effect estimates in single studies. Bias arising from studies with incomplete outcome data is naturally propagated in a meta-analysis. Conventio...
Researchers are concerned whether multiple imputation (MI) or complete case analysis (CCA) should be used when a large proportion of data are missing. We aimed to provide guidance for drawing conclusi...
To investigate the implications of addressing informative missing binary outcome data (MOD) on network meta-analysis (NMA) estimates while applying the missing at random (MAR) assumption under differe...
Mass spectrometry-based metabolomics aims to profile the metabolic changes in biological systems and identify differential metabolites related to physiological phenotypes and aberrant activities. Howe...
This study was designed in order to evaluate the blood pressure lowering effect of valsartan compared to enalapril over 24 hours after skipping one daily dose. Both drugs act on the renin...
Intraoperatively, the surgeon will interrogate the liver with ultrasound. The time spent by the surgeon using the ultrasound is recorded. If all lesions seen on pre-op imaging were found, ...
The aim of this study is to compare two techniques of placing a peripherally inserted central venous catheter (PICC). The first technique, uses ECG based electromagnetic guidance (ECG-EM)....
Background: - Pericardiocentesis uses a needle and small tube to drain fluid from space around the heart. The most common reason to perform this procedure is that the fluid is interfering...
BACKGROUND AND SIGNIFICANCE: Diabetes is a national health problem, yet Latinos from low-income households are at greater risk. Although guidelines recommend that patients learn self-mana...
The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
Individuals who have developed skills, physical stamina and strength or participants in SPORTS or other physical activities.
Communications via an interactive conference between two or more participants at different sites, using computer networks (COMPUTER COMMUNICATION NETWORKS) or other telecommunication links to transmit audio, video, and data.
Works about clinical studies in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).
