Analysis principles
Dataset behaviour before interpretation
Interpretation begins with dataset structure, sample composition, proteome depth, and data completeness.
Replicate coherence and global structure
Replicate consistency and overall data structure are examined early to judge how reliably differences can be interpreted.
Explicit filtering and threshold decisions
Filtering, completeness thresholds, and imputation are treated as analytical choices that shape interpretation.
Quantitative differences in context
Statistical results are considered alongside effect size, replicate consistency, and coverage depth.
Conditional downstream analysis
Functional and enrichment analyses are applied selectively, guided by the strength of the quantitative structure.
Explicit communication of limits
Red flags and limitations are stated clearly, and conclusions stay within what the data can support.
