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 therapeutic transport across the neurovasculature remains a challenge for developing medicine to treat central nervous system (CNS) disorders (Bell and Ehlers, Neuron 81:1-3, 2014). This chapter is meant to provide some insight and key considerations for developing and evaluating various technologies and approaches to CNS drug delivery. First, a brief review of various biological barriers, including the immune system, cellular and protein components of the blood-brain barrier (BBB), and clearance mechanisms in peripheral organs is provided. Next, a few examples and learnings from existing BBB-crossing modalities will be reviewed. Insight from "BBBomic" databases and thoughts on basic requirements for successful in vivo validation studies are discussed. Finally, an additional engineering barrier, namely manufacturing and product scalability, is highlighted as it relates to clinical translation and feasibility for developing BBB-crossing delivery technologies. A goal of this chapter is to provide an overview of the many barriers to the successful delivery of medicines into the brain. An emphasis will be placed on biotherapeutic and gene therapy applications for the treatment of neurological and neurodegenerative disorders.
