Circulating interleukin-23 levels in ankylosing spondylitis and their correlation with disease activity : A meta-analysis.
Synthesis in Zeitschrift fur Rheumatologie, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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 systematically investigate the relationship between circulating interleukin-23 (IL‑23) levels and ankylosing spondylitis (AS) and establish a correlation between these hematological indices and AS activity/severity.
methodsWe searched the Medline, Embase, and Cochrane databases; performed a meta-analysis comparing serum/plasma IL‑23 levels in patients with AS to those of controls; and examined the correlation coefficients between serum/plasma IL‑23 levels and AS activity.
resultsTen studies including 1724 patients with AS and 1589 controls were included in this meta-analysis. This meta-analysis showed that circulating IL‑23 levels were significantly higher in the AS than in the control group (standardized mean difference [SMD] 1.479; 95% confidence interval [CI] 0.308-2.650; p = 0.013). Stratification by ethnicity showed a significantly increased IL‑23 level in the AS group in an Asian population (SMD 1.551; 95% CI 0.543-2.558; p = 0.003). Stratification by adjustment for age and sex revealed significantly higher IL‑23 levels in the AS adjustment group. Subgroup analysis of sample size showed a significantly higher IL‑23 level for a small (n < 150) sample number in the AS group. Meta-analysis of correlation coefficients revealed that the IL‑23 level was positively associated with the Bath Ankylosing Spondylitis Metrology Index (BASMI; correlation coefficient 0.464; 95% CI 0.027-0.752; p = 0.038), erythrocyte sedimentation rate (ESR; correlation coefficient 0.258; 95% CI 0.076-0.422; p = 0.006), and C‑reactive protein (CRP; correlation coefficient 0.291; 95% CI 0.053-0.498; p = 0.017).
conclusionThis meta-analysis demonstrated that the circulating IL‑23 level is significantly higher in patients with AS, and a significant positive correlation exists between the circulating IL‑23 level and BASMI, ESR, and CRP.
