Seasonal 25-hydroxyvitamin D levels in new childhood-onset SLE: associations with disease activity and peripheral lymphocyte subsets.
Article in Lupus science & medicine, 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
objectiveThis study aimed to compare 25-hydroxyvitamin D (25-(OH)D) levels and peripheral lymphocyte subsets between children with new childhood-onset SLE and healthy controls across different seasons, and to explore the relationships of seasonal 25-(OH)D concentrations with the disease activity and peripheral lymphocyte subsets in paediatric patients with SLE.
methodsA retrospective study was conducted, enrolling 285 patients with new childhood-onset SLE and 175 healthy children. All participants were divided into a winter-spring group and a summer-autumn group according to sampling seasons. Serum 25-(OH)D levels and peripheral lymphocyte subsets were detected and quantified.
resultsCompared with healthy controls, patients with SLE presented with significantly higher proportions of CD8
conclusionsSerum 25-(OH)D levels are affected by seasonal changes and closely correlated with disease activity in children with SLE. Patients with new childhood-onset SLE manifest abnormal peripheral lymphocyte subsets and insufficient 25-(OH)D.
