What is a continuous outcome variable?
If a variable can take on any value between its minimum value and its maximum value, it is called a continuous variable; otherwise, it is called a discrete variable. Some examples will clarify the difference between discrete and continuous variables.
Can continuous variables have levels?
Categorical variables are those that have discrete categories or levels. Categorical variables can be further defined as nominal, dichotomous, or ordinal….Get Your Dissertation Approved.

What does a continuous outcome mean?
When a measure is continuous, that is the outcome for each participant consists of a measurement on a numerical scale, the results would usually be summarised as means (the sum of all the measurements divided by the number of participants), and the effect size summarised as the difference between the means of the …
Which is an example of a binary outcome?
Examples include depression status [ 1 ], disease status [ 2 ], and mortality [ 3 ], among others. These binary outcomes may either be true “yes or no” variables (e.g., mortality) or be created from an underlying continuous variable (e.g., when depression status is determined by dichotomizing a psychological scale).
How are binary measures used in clinical trials?
While binary measures are useful for demonstrating a certain level of efficacy in clinical trials, we will show that the loss of information when changing from the underlying continuous scale to the binary outcome measure results in a loss of power to detect differences between treatments in MTC analyses.
Which is less sensitive binary or continuous data?
The information lost when transforming continuous data into a binary response measure translates into a loss of power to detect differences between treatments in mixed treatment comparison models. Binary outcome measures are therefore less sensitive to change than continuous measures.
How is the relative Association of exposure and binary outcome measured?
The relative association of an exposure and binary outcome can be quantified through the use of a ratio measure such as a risk ratio or odds ratio.
