Serum Calprotectin Levels in Different Subtypes of Juvenile Idiopathic Arthritis (JIA) and Its Correlation with Quantitative CRP and JADAS-27.

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
objectiveTo study the serum calprotectin levels in children with juvenile idiopathic arthritis (JIA) and correlate it with C-reactive protein (CRP) and the Juvenile Arthritis Disease Activity Score-27 (JADAS-27).
methodsThis was a cross-sectional observational study done between November 2017 and March 2019. Fifty treatment-naive children, aged 1 to 18 y with the diagnosis of JIA as per the International League of Associations of Rheumatology (ILAR) criteria were enrolled. Assessment of disease activity was done according to the Juvenile Arthritis Disease Activity Score (JADAS-27). Determination of serum calprotectin and CRP levels was done by immunoassay. The correlation between calprotectin levels with CRP and JADAS-27 was calculated.
resultsOf the 50 patients with JIA included in the study, there were 18 female and 32 male children. The median age of presentation to the hospital was 9 y (IQR 5.82-13). The median JADAS-27 was 14 (IQR 6, 20.25). The median serum calprotectin level was 45,375 ng/mL (IQR 30,725, 52,270; range 8,560-63,160 ng/mL). The median CRP was 35.4 mg/L (IQR 3.48, 80.3; range 0.02 and 107.4 mg/L). The levels of calprotectin in different JIA subtypes were not statistically different using Kruskal-Wallis test. The study also demonstrated a positive correlation between serum calprotectin with CRP and the JADAS-27 (r = 0.418).
conclusionThe calprotectin levels in JIA were significantly higher than those reported in the literature irrespective of the subtype. Serum calprotectin positively correlated with CRP and JADAS-27 in children with JIA.
