    The study externally validated the International IgA Nephropathy Prediction Tool in a Thai cohort with biopsy-proven IgA nephropathy.

  • 2

    A total of 133 patients were followed for a median of 3.4 years, with 33.8% reaching the renal endpoint.

  • 3

    The IIgANPT showed good discrimination with C-statistics of 0.753 and 0.754 for models with and without race, respectively.

  • 4

    Calibration was preserved, but confidence intervals around calibration slopes were wide, indicating limited precision.

  • 5

    Both model versions performed similarly, suggesting the race variable's exclusion had minimal impact on prognostic performance.
