Treatment patterns, treat-to-target goals and clinical outcomes of patients with active lupus nephritis: real-world evidence from a multicentre cohort study.
Article in Arthritis research & therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLupus nephritis (LN) is a common and severe manifestation of systemic lupus erythematosus (SLE). We sought to evaluate treatment patterns, treat-to-target state attainment, and outcomes of patients with active LN on non-biologic, conventional therapy, in a large real-world cohort from the Asia–Pacific region.
methodsAdult patients enrolled in a multinational lupus cohort were studied for evidence of active LN, defined based on the SLE Disease Activity Index-2000 (SLEDAI-2K)-proteinuria threshold (> 0.5 g/24 h or > 0.05g/mmol), ≥ 2 visits of data, and no exposure to biologics. The subset of these patients who had kidney biopsy-confirmed LN was retrospectively determined. Attainment of treatment goals, including modified versions of complete renal response (mCRR) and primary efficacy renal response (mPERR), lupus low disease activity state (LLDAS) and DORIS remission (REM), and organ damage accrual, were assessed over time following the first visit with proteinuria.
resultsOne thousand one hundred eighty patients were studied for a median 2.7 [IQR 1.0, 5.0] years, 435 (37%) of whom had biopsies (Class III/IV = 242 (56%)). mCRR, mPERR, LLDAS, and REM were attained at least once during follow-up by 46%, 55%, 60%, and 46% of patients, respectively. mCRR and mPERR attainment was highest at year 2, while LLDAS and REM attainment gradually increased over time. New organ damage accrued in 11% of patients by year 1, increasing to 33% by year 5.
conclusionIn a multinational cohort of patients with active LN receiving non-biologic conventional therapy, the attainment of renal responses, LLDAS, and REM was low, while damage accrual was prevalent.
