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

Traumatic brain injury (TBI) impacts millions of people globally, however currently there are no approved therapeutics that address long-term brain health. In order to create a technology that is relevant for siRNA delivery in TBI after systemic administration, sub-100 nm nanoparticles with rolling circle transcription (RCT) are synthesized and isolated in order improve payload delivery into the injured brain. Unlike conventional RCT-based RNA particles, in this method, sub-100 nm RNA nanoparticles (RNPs) are isolated. To enhance RNP pharmacokinetics, RNPs are synthesized with modified bases in order to graft polyethylene glycol (PEG) to the RNPs. PEGylated RNPs (PEG-RNPs) do not significantly impact their knockdown activity in vitro and lead to longer blood half-life after systemic administration and greater accumulation into the injured brain in a mouse model of TBI. In order to demonstrate RNA interference (RNAi) activity of RNPs, knockdown of the inflammatory cytokine TNF-α in injured brain tissue after systemic administration of RNPs in a mouse model of TBI is demonstrated. In summary, small sub-100 nm multimeric RNA nanoparticles are synthesized and isolated that can be modified using accessible chemistry in order to create a technology suitable for systemic RNAi therapy for TBI.
