まとめ
強度近視児の半数以上が罹患しており、末梢網膜病変は一般的である。軸長が最も強い予測因子であり、小児の強度近視における早期スクリーニングの必要性を強調している。
科学分野:
- 眼科学
- 小児眼科学
- 網膜画像診断
背景:
- 小児の強度近視は、重大な眼合併症と関連している。
- 末梢網膜病変は、網膜剥離の既知のリスク因子である。
研究 の 目的:
- 強度近視児における末梢網膜病変の有病率、種類、および生体計測学的予測因子を決定すること。
- この集団における軸長と末梢網膜病変の関係を評価すること。
主な方法:
- 強度近視の小児89名(4〜17歳)の後ろ向き横断研究。
- 超広角画像および/または散瞳眼底検査を用いた末梢網膜評価。
- 軸長および屈折誤差を含む生体計測データの分析。
主要な成果:
- 末梢網膜病変は眼の54.4%に見られ、年齢とともに増加した。最も一般的な病変は、圧迫なしの暗い病変、圧迫なしの白い病変、カタツムリ跡変性であった。軸長は、病変の有病率(OR=1.45)および複数性(OR=2.17)の最も強い独立した予測因子であった。
- The most common lesions included dark without pressure, white without pressure, and snail-track degeneration.
- Axial length was the strongest independent predictor of lesion prevalence (OR=1.45) and multiplicity (OR=2.17).
結論:
- 末梢網膜病変は小児の強度近視において有病率が高く、軸長と強く相関している。
- リスク層別化および監視において、特に超広角画像を用いた早期末梢網膜評価は、強度近視児において極めて重要である。

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.

Correlations

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 Causation

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...

Correlation
15.2K
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:

Correlation and Regression
3.5K
In statistics, correlation describes the degree of association between two variables. In the subfield of linear regression, correlation is mathematically expressed by the correlation coefficient, which describes the strength and direction of the relationship between two variables. The coefficient is symbolically represented by 'r' and ranges from -1 to +1. A positive value indicates a positive correlation where the two variables move in the same direction. A negative value suggests a...

Coefficient of Correlation

The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...
