However, failure to observe sufficient evidence for rejection of the null hypothesis does not necessarily suggest the equivalence of 2 treatments2). Clinical trial design is an important aspect of interventional trials that serves to optimize, ergonomise and economize the clinical trial conduct. Cerda C, Bruguera M, Pars A. Hepatotoxicity associated with glucosamine and chondroitin sulfate in patients with chronic liver disease. The goal of a clinical study is to assess the safety, efficacy, and / or the mechanism of action of an investigational medicinal product (IMP) or procedure, or new drug or device that is Non-inferiority and equivalence designs are less commonly used in cluster randomized trials. Tenecteplase went into clinical trial comparisons with alteplase as a single bolus thrombolytic. The purpose of the clinical trial is assessment of efficacy, safety, or risk benefit ratio. Warfarin is recommended for patients with thrombotic antiphospholipid syndrome (APS) based on data showing superiority of warfarin over the direct oral anticoagulant (DOAC) rivaroxaban. The superiority trials demonstrate superiority either to a placebo in a placebo-controlled trial or to an active control treatment. Superiority or non-inferiority trials can be conducted only if there is prior information available about the test drug on a specific end point. [6,7,9] These comparisons may prove superiority, non-inferiority or equivalence among groups. The term non-inferiority is now well established, but if taken literally could be misleading. Non-inferiority trials The corresponding null hypothesis is: The new treatment is inferior to the control treatment by a clinically relevant amount. However, failure to observe sufficient evidence for rejection of the null hypothesis does not necessarily suggest the equivalence of 2 treatments2). The objective of an active controlled study may be either to demonstrate the superiority, noninferiority, or equivalence of the new product with the active comparator , . Finally, sample size calculations for clinical trials testing the equivalence rather than the superiority between two treatments need another approach. A scatter plot is a mathematical diagram that uses Cartesian coordinates to display values of a dataset. However, failure to observe sufficient evidence for rejection of the null hypothesis does not necessarily suggest the equivalence of 2 treatments2). The objective of a non-inferiority trial is sometimes stated as being to demonstrate that the test product Ann Rheum Dis 2016;75:37-44. Clinical study design is the formulation of trials and experiments, as well as observational studies in medical, clinical and other types of research (e.g., epidemiological) involving human beings. 3. The superiority trials demonstrate superiority either to a placebo in a placebo-controlled trial or to an active control treatment. Many clinical trials comparing a test product with an active comparator are designed as non-inferiority trials. Dayan et al. PROCEDURE. A number of observations provide context to our conclusions. Since the advent of drug-eluting stents (DES) and the evidence attesting to their superiority over bare metal stents (), several trials have been published investigating PCI outcomes in comparison to CABG.The BEST investigators undertook an RCT to demonstrate non-inferiority of Everolimus eluting stent in respect to CABG.

Clinical trial design is an important aspect of interventional trials that serves to optimize, ergonomise and economize the clinical trial conduct. Both superiority and non-inferiority trials should ideally be designed with a 90% statistical power. In trials conducted prior to the emergence of the Delta and Omicron variants, NVX-CoV2373 efficacy in preventing symptomatic COVID-19 was 90 percent; rare cases of myocarditis were reported among vaccine recipients [10,11].

It has been argued that protocol violations and poorly conducted trials may cause the results obtained from two different treatment groups to appear similar. Ann Rheum Dis 2016;75:37-44. Non-inferiority trials The corresponding null hypothesis is: The new treatment is inferior to the control treatment by a clinically relevant amount. Goal The AZCQ-IPTp pivotal trial is a multicentre, multicountry, phase III, open-label, randomized superiority study of AZCQ-IPTp versus SP-IPTp in pregnant women of sub-Saharan Africa.

The minimal acceptable standard for statistical power in superiority trials generally is 80% with a two-sided alpha of 0.05. The structure of this protocol is different to that used for conventional trials because this trial is highly adaptive and the description of these adaptations is better understood and specified using a modular protocol design.

Based on a mortality rate of 14% in the control group (assuming mortality in observational cohorts may be greater than in trials with exclusion criteria) and a noninferiority margin of 5%, 454 patients were needed in total to achieve 80% power with a 1-sided level of .025, allowing for 10% dropout.

The principles outlined apply to superiority and non-inferiority trials as well as to equivalence trials, though the same biased estimate of the treatment effect may lead to different conclusions for trials with different objectives. In non-inferiority trials this is more crucial, since lower power biases the results towards non-inferiority.

The simplest and most widely used approach to test equivalence is the two one-sided test (TOST) procedure 2.Using TOST, equivalence is established at the significance level if a (12) 100% confidence interval for the difference in efficacies (new current) is contained within the interval (-, ) (Fig. First, very few mantra meditation programs met our inclusion criteria.
