Clinical trial randomization is the process of assigning patients by chance to groups that receive different treatments. At several points during and at the end of the clinical trial, researchers compare the groups to see which treatment is more effective or has fewer side effects. ... Why are ...
Blinding is used in approximately 60% of randomizedclinical trials(Chan and Altman, 2005). Blinding patients and health-care providers can be difficult or in some cases impossible. For example, it is difficult to imagine how to blind patients in trials that evaluate the effect of jogging on...
Methods: We searched CENTRAL, MEDLINE, EMBASE, SinoMed, CNKI, VIP, China Important Conference Papers Database, China Dissertation Database, and online clinical trial registry websites for published and unpublished randomized clinical trials (RCTs) of CPMs for the common cold till 31 March 2013.

Controlled Clinical TrialsBouzy, J.; Kramar, A.; Lambin, P. The difficulties in the data management of recurrent and transient events in pro- spective randomized clinical trials: Example from a ran- domized trial comparing two different brachytherapy dose- rates in gynaecological cancer (Abstract ...
For example, the guideline-recommended BP target is generally less than 130/80 mmHg for patients with stable cardiovascular disease33,34. Even in the SPRINT trial, where a standardized BP measurement was done, the mean systolic BP of the intensive treatment arm was 121 mmHg35. It is, ...
An example using data from a longitudinal randomized clinical trial illustrates the use of the methods in a practical setting. It is shown that even when responses on different sets of items for different groups of patients are used for the data analysis, the power to detect the experimental ...
This randomized clinical trial evaluates the effect of a communication-priming intervention designed to increase patient-reported goals-of-care
Clinical trial design has dramatically evolved with the advent of precision medicine. As a result, expedited drug-approval decisions have been made on the basis of evidence obtained in uncontrolled clinical trials. Herein, Saad et al. discuss the need to
Compliers (C), who fully take the experimental treatment when assigned to it, and fully take the control treatment when assigned to it: (Ti, Pi) = (1, 1) and (Ti, Pi) = (0, 0); for example, in a standard clinical trial of a new drug versus placebo, these are the pa...
The resistance training consisted of three sets in the main muscle groups, for example, chest press, leg press, back row, and leg extension. The 8–12 repetitions aimed at a resistance consistent with 0–3 repetitions in reserve46. All heart-rate profiles were recorded during the exercise ...
