Differences between groups in the outcome variable(s) are believed to be the result of the differing interventions. The primary outcome is the outcome of greatest importance. Data on secondary outcomes are used to evaluate additional effects of the intervention.
Also asked, what is a secondary outcome measure?
SECONDARY OUTCOME MEASURE. A planned outcome measure in the protocol that is not as important as the primary outcome measure, but is still of interest in evaluating the effect of an intervention. Most clinical studies have more than one secondary outcome measure.
Subsequently, question is, what does primary outcome mean? The primary outcome measure is the outcome that an investigator considers to be the most important among the many outcomes that are to be examined in the study. The primary outcome needs to be defined at the time the study is designed.
People also ask, what is primary outcome and secondary outcome?

What is the difference between primary and secondary endpoints?
The primary endpoint of a clinical trial is the endpoint for which the trial is powered. Secondary endpoints are additional endpoints, preferably also pre-specified, for which the trial may not be powered.

What are examples of outcome measures?
Outcome measures reflect the impact of the health care service or intervention on the health status of patients. For example: The percentage of patients who died as a result of surgery (surgical mortality rates). The rate of surgical complications or hospital-acquired infections.Can you have more than one primary outcome?
Some trials may have more than one primary outcome. Having several primary outcomes, however, incurs the problems of interpretation associated with multiplicity of analyses (see items 18 and 20) and is not recommended. Primary outcomes should be explicitly indicated as such in the report of an RCT.Why are secondary endpoints studied?
A Secondary endpoint has secondary objectives. For example, a drug designed to prevent allergy-related deaths might also have a measure of whether quality of life is improved. A Secondary endpoint is therefore always paired with a primary one.What makes a good outcome measure?
Outcome variables should be collected at a rate that reflects the dynamic nature of change resulting from, for example, a physical or behavioral intervention. A trajectory of change may be linear or non-linear. Change in outcomes may be rapid early in treatment, then stabilize, and then show another shift.What are study outcomes?
Outcomes (also called events or endpoints) are variables that are monitored during a study to document the impact that a given intervention or exposure has on the health of a given population. Typical examples of outcomes are cure, clinical worsening, and mortality.What is a primary composite outcome?
Composite outcomes, in which multiple end points are combined, are fre- quently used as primary outcome measures in randomized trials and are of- ten associated with increased statistical efficiency.Is primary outcome the same as primary endpoint?
The term outcome usually refers to the measured variable (eg, peak volume of oxygen or PROMIS Fatigue score), whereas an endpoint refers to the analyzed parameter (eg, change from baseline at 6 weeks in mean PROMIS Fatigue score).What is secondary objective in clinical trial?
Clinical trials typically have a primary objective or endpoint. Additional objectives and endpoints are secondary. The sample size calculation is based on the primary endpoint. Analysis involving a secondary objective has statistical power that is calculated based on the sample size for the primary objective.What are outcome measures in a research study?
An outcome measure, endpoint, effect measure or measure of effect is a measure within medical practice or research, (primarily clinical trials) which is used to assess the effect, both positive and negative, of an intervention or treatment.

The outcome of a study is a broad term for any defined disease, state of health, health-related event or death. In some studies, there may be mul- tiple outcomes.

Exploratory endpoints may include clinically important events that are expected to occur too infrequently to show a treatment effect or endpoints that for other reasons are thought to be less likely to show an effect but are included to explore new hypotheses.How do you measure outcomes?
