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
Introduction: The clinical efficacy of Janus kinase inhibitors (JAKinibs) is highly variable and their safety profiles are poorly understood. Methods: We established two flow cytometry panels for the assessment of two promising leukocyte biomarkers: signal transducer and activator of transcription (STAT) phosphorylation and cytokine receptor expression. We evaluated the first panel, which assesses phosphorylation levels for STAT1, STAT3, and STAT5 after cytokine stimulation, with or without Results: Stimulation with interleukin (IL)-2 or IL-7 increased STAT5 phosphorylation in T cells but not in B cells or monocytes. IL-6 stimulation induced STAT3 phosphorylation in monocytes and CD4 T cells and, to a lesser extent, in CD8 T cells, but not in B cells. IL-21 stimulation led to STAT3 phosphorylation in T cells and, to a lesser extent, in B cells, but not in monocytes. Interferon-α stimulation increased STAT1 phosphorylation in all cell types. STAT phosphorylation levels were lower after pretreatment with JAKinibs. A dose-response curve was plotted, confirming the correlation between JAKinib concentration and STAT phosphorylation inhibition. The second panel showed that each cell type displayed a distinct pattern of cytokine receptors expression, and that this pattern might be modified by Conclusion: This preliminary study confirms the utility of flow cytometry for monitoring the biological effects of JAKinibs. Further studies on treated patients are now required to evaluate the clinical value of these two flow cytometry panels.
