まとめ
本研究では、reflimR法を用いてトルコ人成人の参照基準値(RI)を検証し、集団の違いにより製造元のRIとの乖離が見られた。reflimRアルゴリズムは、RIの計算と検証にアクセス可能な方法を提供する。
科学分野:
- 臨床生化学; 検査医学; 公衆衛生
背景:
- 正確な参照基準値(RI)の確立は、臨床検査結果の解釈に不可欠である。; 製造元提供のRIは、多様な集団を正確に反映していない可能性があり、地域的な検証が必要である。; reflimR法は、間接RI推定および検証のための新しいアプローチを提供する。
研究 の 目的:
- トルコ人成人集団における19項目の日常生化学検査の参照基準値(RI)を検証する。; reflimR法を用いて導出されたRIと製造元提供のRIを比較する。; reflimRアルゴリズムの性能を他の間接RI推定法と比較評価する。
主な方法:
- Beckman Coulterアナライザーで分析された19項目の生化学パラメータのRIを評価するためにreflimRアルゴリズムを利用した。; 男性および女性のRI推定のために、5つの間接アプローチ(reflimR、refineR、KOSMIC、Hoffmann、Bhattacharya)を採用した。; RI限界検証のために、許容不確実性に基づくトラフィックライトアルゴリズムを適用した。
主要な成果:
- reflimRによって計算された76のRI限界のうち40が受理され、21は確認が必要で、15は製造元の値と比較して却下された。; reflimR法は、ALT、GGT、総ビリルビンを除き、他の間接法と一般的に一致した結果を示した。; 検証の失敗は、集団間の民族、性別、年齢、地理的な変動の可能性を浮き彫りにした。
結論:
- reflimRアルゴリズムは、RIの計算と検証のための迅速かつアクセス可能なツールを提供する。; RIの乖離は、集団特異的な検証の重要性を強調する。; 民族性や人口統計などの要因は、RIの確立に大きく影響する。

Self-Evaluation: Self-Enhancement and Self-Verification
5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Prediction Intervals
3.4K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Strategies of Self-Presentation II: Self-Verification
205
Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Confidence Intervals
10.8K
An unbiased point estimate is often insufficient to predict a population estimate, such as population mean or population proportion. In this scenario, a confidence interval is used. A confidence interval is an estimate similar to a sample proportion. However, unlike the point estimate which is a single value, the confidence interval contains a range of values. These values have lower and upper limits, known as confidence limits, and can be designated as L1 and L2, respectively.

Inertial Frames of Reference
8.9K
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...

Non-inertial Frames of Reference
7.2K
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...
