    Reproducibility in environmental epidemiology may reflect shared seasonal patterns rather than distinct causal effects.

  • 2

    Causal inference is heavily influenced by how seasonal structure is statistically represented in environmental time-series studies.

  • 3

    Different seasonal adjustment methods can significantly alter estimated associations between temperature, air pollution, and mortality.

  • 4

    Collinearity among seasonal variables limits the ability to distinguish between correlated predictors in environmental studies.

  • 5

    Greater transparency in modeling choices is essential for accurate interpretation of environmental epidemiological evidence.
