The guideline is not intended to give a detailed understanding of the meta-analytic techniques described, but rather to explain the main strengths and weaknesses of the methodologies. The guideline discusses some common issues in meta-analysis that must be considered when interpreting results.
This directive provides guidelines for ensuring the highest standards of quality and integrity in clinical research. In the European Union, a parallel guideline exists for clinical trials involving medical devices. This guideline is known as the international standard ISO 14155, and it serves as a harmonized standard within the European Union ...
The rules are intended to eliminate certain C coding practices which make code difficult to review or statically analyze. These rules are a complement to the MISRA C guidelines and have been incorporated into the greater set of JPL coding standards. [2]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
The fundamental prevalence-independent statistics are sensitivity and specificity.. Sensitivity or True Positive Rate (TPR), also known as recall, is the proportion of people that tested positive and are positive (True Positive, TP) of all the people that actually are positive (Condition Positive, CP = TP + FN).
Specificity (true negative rate) is the probability of a negative test result, conditioned on the individual truly being negative. If the true status of the condition cannot be known, sensitivity and specificity can be defined relative to a " gold standard test " which is assumed correct.
Youden's J statistic is = + = + with the two right-hand quantities being sensitivity and specificity.Thus the expanded formula is: = + + + = (+) (+) In this equation, TP is the number of true positives, TN the number of true negatives, FP the number of false positives and FN the number of false negatives.
Validity is the main extent to which a concept, conclusion, or measurement is well-founded and likely corresponds accurately to the real world. [1] [2] The word "valid" is derived from the Latin validus, meaning strong.
