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

Efficient delivery of small interfering (si)RNA to specific cell populations in vivo remains a formidable challenge to its successful therapeutic application. We show that siRNA synthetically linked to a CpG oligonucleotide agonist of toll-like receptor (TLR)9 targets and silences genes in TLR9(+) myeloid cells and B cells, both of which are key components of the tumor microenvironment. When a CpG-conjugated siRNA that targets the immune suppressor gene Stat3 is injected in mice either locally at the tumor site or intravenously, it enters tumor-associated dendritic cells, macrophages and B cells. Silencing of Stat3 leads to activation of tumor-associated immune cells and ultimately to potent antitumor immune responses. Our findings demonstrate the potential of TLR agonist-siRNA conjugates for targeted gene silencing coupled with TLR stimulation and immune activation in the tumor microenvironment.
