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

Objective: This study aimed to investigate the link between circulating interleukin-18 (IL-18) levels and adult-onset Still's disease (AOSD). Methods: A thorough search was performed on MEDLINE, Embase, and Web of Science to find relevant articles. A meta-analysis was conducted to compare serum/plasma IL-18 levels in AOSD patients to those in control subjects. Results: The meta-analysis included 13 studies with a total of 562 AOSD patients and 790 controls. The results showed a significant increase in IL-18 levels in the AOSD group compared to the control group (standard mean difference [SMD]=1.899, 95% confidence interval [CI]=1.078~2.720, p<0.001). When stratified by ethnicity, higher IL-18 levels were found in both Asian and European populations with AOSD. Subgroup analysis, regardless of variable adjustments, consistently indicated significantly higher IL-18 levels in the AOSD group. Significant elevations in IL-18 levels were observed in both small (n<50) and large groups (n>50), as well as in original and imputed data groups after data type stratification. Free IL-18 levels were significantly higher in the active group compared to the inactive group (SMD=0.900, 95% CI=0.532~1.268, p<0.001). The meta-analysis showed a positive correlation between IL-18 levels and ferritin (correlation coefficient=0.542, 95% CI=0.431~0.637, p<0.001) and C-reactive protein. Conclusion: This meta-analysis demonstrated a significant increase in circulating IL-18 levels and a positive correlation between IL-18 levels and ferritin and C-reactive protein levels in patients with AOSD.
