Document disclaimer This document offers a set of post-publication reflections on the Three-Level Model of diffuse idiopathic skeletal hyperostosis (DISH). It is not intended to serve as a supplementary manuscript or a duplicate account of the published studies. No tables, figures, or additional empirical analyses are included here, and readers seeking the full methodological details, statistical results, and visual representations of the model are referred to the original peer-reviewed publications. Rather, these reflections aim to trace the intellectual route by which a decade of work on DISH gradually converged into a hierarchical framework integrating latent susceptibility, downstream biological activation, and phenotypic resolution. Some sections remain closely grounded in the empirical evidence reported in the published article and related publications from the Camargo Cohort, whereas others move deliberately into conceptual interpretation and biologically plausible hypotheses that emerged from those findings. This distinction is important: the document aims neither to overextend the original data nor to dilute its evidential core, but to make explicit the reasoning, uncertainties, and open questions that have shaped this research programme and may guide its next stage. This Introduction has been added to help readers contextualise the document. Composed of seven parts, the document has been developed with the aim of sharing experiences and providing insight into DISH essentials.
