Question: What Does Doubtful Clinical Significance Mean?

In a brain MRI report, the following words often appear: “clinical correlation is recommended”.

These words signify that inadequate clinical information was provided, or that an unexpected finding on the MRI should be assessed clinically..

How do you know if results are clinically significant?

It is calculated by taking the difference between group means divided by the standard deviation. The larger the number, the stronger the beneficial effect. Don’t just look at the p value. Try to decide if the results are robust enough to also be clinically significant.

What is clinical value?

CLINICAL VALUE COMPASS APPROACH: The clinical Value Compass, named to reflect its similarity in layout to a directional compass, has at its four cardinal points (1) functional status, risk status, and well-being; (2) costs; (3) satisfaction with health care and perceived benefit; and (4) clinical outcomes.

What are clinical implications?

The clinical implications include attention bias, interpretation bias, reduced evidence of danger (RED) bias, memory bias, origins of cognitive distortions, cognitive bias modification in children and adults, and facilitating self-disclosure.

What does it mean that the results are not statistically significant for this study?

This means that the results are considered to be „statistically non-significant‟ if the analysis shows that differences as large as (or larger than) the observed difference would be expected to occur by chance more than one out of twenty times (p > 0.05).

How is correlation defined?

Correlation means association – more precisely it is a measure of the extent to which two variables are related. … Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases. An example of positive correlation would be height and weight.

What does it mean to be clinically significant?

Clinical significance is the practical importance of an effect (e.g. a reduction in symptoms); whether it has a real genuine, palpable, noticeable effect on daily life.

How do you know if something is statistically significant?

To carry out a Z-test, find a Z-score for your test or study and convert it to a P-value. If your P-value is lower than the significance level, you can conclude that your observation is statistically significant.

Do radiologist tell you results?

Most patients have their results within 48 hours. Also, Edwards said, patients can request a copy of their results after the radiologist reads the test. “People do have a right to see their reports,” she said.

What is the cutoff value to determine if a treatment effect is present?

Traditionally, researchers have used probabilities <5% (1.96 SE) or <1% (2.56 SE) as cutoffs.

Why is clinical significance important?

[1] Measures of statistical significance quantify the probability of a study’s results being due to chance. … In clinical practice, the “clinical significance” of a result is dependent on its implications on existing practice-treatment effect size being one of the most important factors that drives treatment decisions.

Can you have clinical significance without statistical significance?

significant. across multiple patient populations, the statistically significant result may be only minimally useful and thus isn’t clinically significant. If a statistically significant result isn’t clinically significant, it’s not clinical- ly helpful and shouldn’t be used to guide clinical practice.

How often do radiologists make mistakes?

Errors and discrepancies in radiology practice are uncomfortably common, with an estimated day-to-day rate of 3–5% of studies reported, and much higher rates reported in many targeted studies.

Can a radiographer tell you results?

Radiographers are not able to give results directly to the patient.

What does no acute findings mean on CT scan?

The researchers found the scan results prompted doctors to change their diagnoses in nearly half the 584 cases. There was a 126 percent increase in a diagnosis of “no acute condition,” meaning there was nothing critically wrong with the patient.

What is the clinical significance of bilirubin?

This test measures the amount of bilirubin in the blood to evaluate a person’s liver function or to help diagnose anemias caused by RBC destruction (hemolytic anemia). RBCs normally degrade after about 120 days in circulation. Bilirubin is formed as the liver breaks down and recycles aged red blood cells.

What is the P value in clinical trials?

DEFINITION OF THE P-VALUE In statistical science, the p-value is the probability of obtaining a result at least as extreme as the one that was actually observed in the biological or clinical experiment or epidemiological study, given that the null hypothesis is true [4].

What is a clinically significant odds ratio?

Clinical Significance The odds ratio is the ratio of the odds of the event happening in an exposed group versus a non-exposed group. The odds ratio is commonly used to report the strength of association between exposure and an event. The larger the odds ratio, the more likely the event is to be found with exposure.

What is clinical and biochemical correlation?

Biochemical and molecular results were correlated with clinical features. … Conclusions: This study indicates a close relationship between tissue heteroplasmy, expression of the biochemical defect in platelets, and clinical involvement.

What is CT correlation?

Abstract. Objectives: To correlate the measured dimensions of urinary stones from spiral non-contrast computerized tomography (CT) with that of plain radiography (KUB). … Measurements between imaging modalities were blinded and performed consecutively by a dedicated investigator.

What is an example of clinical significance?

In clinical trials, the clinical significance (“treatment effects”) is how well a treatment is working. For example, a drug might be said to have a high clinical significance if it is having a positive, measurable effect on a person’s daily activities.
