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
The global COVID-19 pandemic has led to significant advancements in vaccine research, particularly regarding patients with autoimmune inflammatory rheumatic diseases (AIIRD). However, most studies have assessed the post-vaccination cellular response only by measuring the production of interferon-gamma. This study aimed to explore the post-vaccination cellular immune response in patients with AIIRD, with a focus on the effects of immunomodulatory drugs on different proteins involved in the cellular response and cytotoxicity. We analyzed blood samples from 54 patients - 16 healthy controls (HC) and 38 AIIRD patients - at three time points: before (T0), 4 weeks after (T1), and more than 6 months after (T2) a COVID-19 booster vaccination. Gene expression and concentration levels of 13 proteins involved in cellular immunity were assessed. Our study showed significantly reduced production of TNF at T0, IL-2 at T0 and T2, and perforin at T2 in AIIRD patients compared to HC. In AIIRD patients the expression of genes involved in cytotoxicity, including NRF2, TRAIL, cathepsin B, and cathepsin H was impaired. Both protein concentrations and gene expression were particularly altered in those treated with glucocorticoids, methotrexate, and biologic/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Among b/tsDMARDs only IL-17 inhibitors did not affect the cellular response. These findings suggest that COVID-19 vaccination elicits a weakened cellular response in patients with AIIRD, particularly those on immunosuppressive therapies, potentially compromising vaccine efficacy. Further studies are required to determine the clinical impact of these findings on long-term vaccine effectiveness in this population.
