Clinical characteristics, disease flares, infections and their impact on kidney outcomes in pediatric lupus nephritis: A cohort study.
Article in Pediatric nephrology (Berlin, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundLimited data exists on clinical predictors of kidney outcomes in children with lupus nephritis (LN).
methodsChildren aged below 18 years with biopsy-proven LN followed from January 2010 to February 2024 in a tertiary-care center were enrolled in order to characterize their clinical presentations, flares, infections, histology and determine Major Adverse Kidney Events (MAKE) (defined as eGFR < 60 mL/min/1.73 m
resultsSeventy-five children (20% boys) with median (IQR) age at diagnosis 11.2 (9,13) years, were studied. Clinical presentations were nephritic syndrome, mixed nephritic-nephrotic features, rapidly progressive glomerulonephritis (RPGN), and nephrotic syndrome in 24 (32%), 15 (20%), 11 (14.7%) and 5 (6.7%) patients, respectively. Proliferative LN was the major (70.6%) histological subtype. In total, 75 kidney flares (21.3% nephritic) with incidence rate (IR) of 0.48 flares per person-year were noted in 31 (41.3%) children. Infections occurred in 32 (42.6%), with IR of 0.58 episodes per person-year. Bacterial pneumonia 14 (22.9%), sepsis 10 (16.3%) and tropical infections 6 (9.8%) were most common. At median last follow-up of 2.3 (1.3, 5.6) years with 85.4% kidney-survival rate, 41 (54.6%), and 21 (28%) were in complete-response (CR), and partial-response (PR), respectively. Proliferative LN and those in PR or NR were at significantly higher risk of kidney flares and infections, regardless of initial induction therapy. RPGN at presentation, non-responders at 6 months and severe kidney flare ever predicted MAKE in 11 (14.6%) children.
conclusionsMultiple kidney flares and infections constitute a significant morbidity in LN. RPGN, non-responders and severe kidney flare predict adverse kidney outcomes.
