Systemic Inflammatory Biomarkers in Alopecia Areata: The Role of SII, SIRI, and CRP/Albumin Ratio.

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
introductionAlopecia areata (AA) is an autoimmune disorder, with potential roles of both genetic and environmental factors. Although AA is a specific autoimmune disease targeting hair follicles, its frequent association with other autoimmune diseases supports the notion that the autoinflammation is not confined to the hair follicles but is systemic. Systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and CRP (C-reactive protein) albumin ratio (CAR) are elevated in various diseases and correlate with disease severity.
objectivesThe aim of this study was to determine SII, SIRI, and CAR levels in alopecia areata patients and investigate their correlation with disease severity.
methodsThe data of 118 AA patients and 122 healthy controls were analyzed. Complete blood count (CBC), CRP, and albumin values were noted during clinic visits. CAR, SII, and SIRI were calculated in both groups.
resultsAlthough median SIRI and CAR levels were higher in the AA group, the difference was not statistically significant (P>0.05). However, median SII was significantly higher in the AA group (P<0.001). AA patients were divided into two groups according to disease severity: mild disease group (MD) and moderate and severe disease (MSD) group. SII, SIRI, and CAR did not differ between the two groups.
conclusionsIn AA patients, SIRI and CAR did not show significant differences compared to the normal population, while SII was significantly higher. SII was not found to be associated with disease severity, suggesting that systemic inflammation may occur even in the mildest cases of the disease.
