This study aimed to develop a prognostic model for poor renal outcomes in patients of mestizo descent.</p><p><strong>Methods: </strong>We conducted a multicentre, retrospective analysis including 290 adult mestizo patients with incident, biopsy-proven pure proliferative LN (International Society of Nephrology/Renal Pathology Society (ISN/RPS) class III or IV) from nine Chilean hospitals. Clinical, biological and histological variables were assessed. The primary outcome was a composite of stage IV/V chronic kidney disease, dialysis or death. Predictive variables were selected using multivariable Cox regression, and prognostic scores were derived accordingly. Internal validation was performed via bootstrapping. External validation included 93 Mexican patients, with model performance assessed using Harrel's concordance index.</p><p><strong>Results: </strong>Two baseline factors were independently associated with poor renal outcome: estimated glomerular filtration rate <30 mL/min/m<sup>2</sup> (HR 3.82, 95% CI 2.15 to 6.78; p<0.001) and histological chronicity index >2 (HR 2.01, 95% CI 1.18 to 3.43; p=0.01). Patients were stratified into three risk categories according to the presence of none (low risk), one (intermediate risk) or both (high risk) of these factors. The likelihood of the primary outcome increased progressively across these groups: high versus intermediate risk (HR 3.22, 95% CI 1.64 to 6.34; p=0.001), and intermediate versus low risk group (HR 2.41, 95% CI 1.35 to 4.30; p=0.003).
