Correlations02:20

Correlations

35.9K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation01:27

Correlation and Causation

42.6K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Introduction to z Scores

11.2K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

z Scores and Area Under the Curve

19.6K
z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...

Correlation

15.1K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Area of Science:

  • Rheumatology
  • Medical Imaging
  • Inflammatory Diseases

Background:

  • Early rheumatoid arthritis (RA) diagnosis and monitoring are crucial for effective management.
  • Musculoskeletal ultrasonography (MSK US) offers a non-invasive method to visualize joint inflammation.

Observation:

  • This study assessed synovial inflammation using MSK US in 29 early RA patients.
  • Grey scale (GSUS) and power-Doppler (PDUS) ultrasonography were employed to evaluate synovitis.
  • Clinical and laboratory assessments were performed alongside ultrasonography.

Findings:

  • Active synovitis was detected in all early RA patients via ultrasonography.
  • Inflammatory markers showed significant correlations with both GSUS and PDUS findings.
  • GSUS and PDUS parameters demonstrated a moderate positive correlation with disease activity scores.

Implications:

  • Ultrasonography is a sensitive and reliable tool for detecting inflammatory activity in early RA.
  • MSK US complements clinical and biological assessments in routine RA evaluation.
  • Integrating ultrasonography into routine practice can enhance early RA patient management.
