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
MicroRNAs (miRNAs) are small noncoding RNA molecules that function as posttranscriptional regulators of gene expression. Kaposi's sarcoma (KS)-associated herpesvirus (KSHV), a B-cell-tropic virus associated with KS and B-cell lymphomas, encodes 12 miRNA genes that are highly expressed in these tumor cells. One viral miRNA, miR-K12-11, shares 100% seed sequence homology with hsa-miR-155, an oncogenic human miRNA that functions as a key regulator of hematopoiesis and B-cell differentiation. So far, in vitro studies have shown that both miRNAs can regulate a common set of cellular target genes, suggesting that miR-K12-11 may mimic miR-155 function. To comparatively study miR-K12-11 and miR-155 function in vivo, we used a foamy virus vector to express the miRNAs in human hematopoietic progenitors and performed immune reconstitutions in NOD/LtSz-scid IL2Rγ(null) mice. We found that ectopic expression of miR-K12-11 or miR-155 leads to a significant expansion of the CD19(+) B-cell population in the spleen. Subsequent quantitative PCR analyses of these splenic B cells revealed that C/EBPβ, a transcriptional regulator of interleukin-6 that is linked to B-cell lymphoproliferative disorders, is downregulated when either miR-K12-11 or miR-155 is ectopically expressed. In addition, inhibition of miR-K12-11 function using antagomirs in KSHV-infected human primary effusion lymphoma B cells resulted in derepression of C/EBPβ transcript levels. This in vivo study validates miR-K12-11 as a functional ortholog of miR-155 in the context of hematopoiesis and suggests a novel mechanism by which KSHV miR-K12-11 induces splenic B-cell expansion and potentially KSHV-associated lymphomagenesis by targeting C/EBPβ.
