Here, we evaluate a milder CP model using only 42 cerulein injections administered in both male and female C57BL\/6J (BL6) and BALB\/c mice. We further assess the therapeutic potential of the ROR\u03b3t inhibitor GSK805. We employed a multi\u2010tiered analytical approach, including the robustness of conclusion (RC), unit fragility index, and robustness index, to evaluate consistency and numerical stability of conclusions. The model reliably produced key hallmarks of CP: reduced pancreas\u2010to\u2010body weight ratio, elevated collagen I deposition, and tubular complex formation with an RC of 100%.
