1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND/

objectivesThis study aimed to analyze the allele frequencies and genotype distributions of key FKBP4 single nucleotide polymorphisms (SNPs) (rs11833878, rs1981655, and rs41456246) in pediatric systemic lupus erythematosus (pSLE) patients versus healthy controls and to evaluate their association with glucocorticoid (GC) treatment efficacy.

methodsForty-five patients with pSLE and 45 age- and sex-matched healthy controls were recruited between October 2022 and June 2024. Genotyping was performed using the imLDR

resultsGenotypes at rs11833878 and rs41456246 were significantly correlated with clinical indicators. rs11833878 was associated with a significant difference in baseline platelet (PLT) count (P = 0.037) and PLT improvement at 3 months (P = 0.016). From baseline to 6 months, it correlated with SLEDAI-2K reduction (P = 0.019) and PLT change (P = 0.035). Between 3 and 6 months, it was associated with a 24-hour urinary protein reduction (P = 0.047). rs41456246 was associated with a significant difference in baseline white blood cell (WBC) count (P = 0.011) and GC dosage at 3 months (P = 0.029). From baseline to 6 months, it correlated with the magnitude of GC tapering (P = 0.021) and PLT improvement (P = 0.034). Between 3 and 6 months, it was associated with the extent of GC tapering (P = 0.011). No significant associations were found for rs1981655.

conclusionFKBP4 polymorphisms may modulate the therapeutic response in pSLE, potentially influencing GC receptor function. rs11833878 was linked to improvements in PLT, SLEDAI-2K score, and proteinuria, whereas rs41456246 was associated with WBC, GC dosage, and PLT recovery. Genotyping these loci may serve as a valuable reference for developing personalized treatment strategies.
