Evaluating Chronicity Scores for Outcomes in Patients With Lupus Nephritis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The aim of this study was to evaluate the prognostic value of the Mayo Clinic Chronicity Score (MCCS) compared with the National Institutes of Health (NIH) Chronicity Index (NIH-CI) in lupus nephritis (LN). Methods: We conducted a retrospective cohort study of 307 patients with biopsy-proven LN evaluated at Mayo Clinic (1992-2023). Chronic histologic injury was graded using the NIH-CI and MCCS. Outcomes were proteinuria remission < 500 mg/d (PR500), complete renal response (CRR), end-stage kidney disease (ESKD), and all-cause mortality. Sex-stratified, age-adjusted Cox models were used. Prognostic performance was evaluated using change in Harrell's C-index (ΔC over a clinical model) and decision-curve analysis was used to assess clinical utility for 5-year ESKD. Subgroup analyses were used to test for effect modification by baseline estimated glomerular filtration rate (eGFR) (< 60 vs. ≥ 60 ml/min per 1.73 m Results: Higher NIH-CI and MCCS scores were associated with lower likelihood of PR500 and CRR (hazard ratio [HR]: 0.75 for both) and greater risk of ESKD (HR: 1.40 for NIH-CI; 1.33 for MCCS). Adding either score to a clinical model improved discrimination for PR500 (C-index: 0.65 to 0.71), CRR (0.64 to 0.71), and ESKD (0.81 to 0.85), but not mortality (ΔC = 0.00). Decision-curve analysis showed similar net benefits for NIH-CI and MCCS. Interstitial fibrosis (IF) and tubular atrophy (TA) (IF/TA) were the only components independently predictive of renal outcomes. Our findings support applicability of both scores in nonproliferative LN and in patients with reduced baseline kidney function. Conclusion: The MCCS and NIH-CI provide comparable and additive prognostic information in LN. MCCS captured the chronic lesions most strongly associated with renal outcomes, with IF/TA as the principal determinant of prognosis.
