WebNext, PCa patients were separated by their median of serum GP88 level in two groups (low: ≤44.56 ng/mL vs high levels: >44.56 ng/mL). Low serum GP88 levels were more often detected in younger patients (≤66 years) and high levels in elder patients (>66 years; P =0.018; Fisher’s exact test). The Gleason scores (GS) of the PCa patients were ...

WebNov 7, 2024 · PCA helps to assess which original samples are similar and different from each other. PCA preserves the global data structure by forming well-separated clusters but can fail to preserve the similarities within the clusters. PCA works better in revealing linear patterns in high-dimensional data but has limitations with the nonlinear dataset. WebDec 22, 2024 · PCA vs LDA.
