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
backgroundHigh levels of circulating interleukin (IL)-16 are associated with a reduced incidence of cardiovascular events. The disruption of atherosclerotic plaques commonly causes myocardial infarction and stroke. In this study, we investigated the effects of IL-16 on phenotypic modification of plaques.
methodsMice with deficiencies in IL-16 and apolipoprotein E (IL16
resultsIL-16 deficiency increased the necrotic core and reduced fibrous cap thickness in the plaques. IL-16 deletion accelerated the degradation of intraplaque collagen and elastin, increased matrixmetalloproteinase activity, and reduced TIMP-3 expression. Transplantation of wild-type IL-16 bone marrow into IL-16 knockout mice successfully attenuated the plaque instability caused by IL16 deficiency. Furthermore, hematopoietic-derived IL-16 activated the CD4/JAK2/STAT6 pathway and increased the binding of STAT6 to the coactivator cAMP-response element-binding protein (CBP)/p300 at the TIMP-3 promoter in smooth muscle cells (SMCs). Consequently, acetylation of STAT6 and histone H3 increased more than 2-fold, which caused a 2.2-fold upregulation of TIMP-3. Moreover, the anti-atherosclerotic effects of IL-16 on plaque stability were abrogated by the SMC-specific deletion of CD4, and the plaque vulnerability caused by IL-16 defects was reversed by SMC-specific overexpression of TIMP-3.
conclusionsIL-16/CD4/JAK2/STAT6 upregulates TIMP-3 expression in SMCs to remodel the intraplaque extracellular matrix toward a stable phenotype. Our findings suggest that IL-16 is a novel factor in vascular remodeling and atherosclerotic plaque phenotype modulation and is a potential target for intervention in the later stages of atherosclerosis.
