  "abstract": "Introduction: Artificial intelligence has been widely applied to chronic kidney disease (CKD), but the term ‘prediction” is frequently used for tasks ranging from contemporaneous disease classification to genuine forecasting of future renal outcomes. This systematic review examined this distinction while evaluating methodological quality and evidence for clinical translation.\n\nMethods: A predefined Scopus-based search covering 2021–2026 identified eligible AI- and machine-learning-based CKD studies. After screening and duplicate reconciliation, 169 unique primary studies were included. Future-oriented prediction required an identifiable baseline, predictors available at or before baseline, a subsequent renal outcome, and a meaningful prediction horizon. Studies were evaluated for modeling approaches, datasets, validation, calibration, explainability, clinical usefulness, and methodological quality using PROBAST+AI.\n\nResults: Of 169 studies, 122 (72.2%) addressed current-state CKD detection or classification, while only 46 (27.2%) contained a clearly future-oriented prediction component. Seventeen studies used geographic or institutional external validation and only four used an independent external cohort or dataset. Calibration was assessed in 12 studies and explicit explainability methods were reported in 16. PROBAST+AI identified high overall risk of bias in 156 studies during development and 164 during evaluation, with no study achieving an overall low-risk judgement.\n\nDiscussion: CKD-AI evidence is substantially stronger for retrospective classification than for genuine early prediction or clinical translation. Future research should prioritize longitudinal prediction, independent and temporal validation, leakage-resistant analysis, calibration, clinically validated explainability, and prospective real-world evaluation.",
