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

The blood-brain barrier (BBB) is a tight barrier that is critical for preventing the entry of pathogens and small molecules into the brain. HIV protein Tat (Tat) is known to disrupt the tight junctions of the BBB. Autophagy is an intracellular process that involves degradation and recycling of damaged organelles to the lysosome and has recently been implicated in the BBB disruption. The role of autophagy in Tat-mediated BBB disruption, however, remains elusive. Herein we hypothesized that Tat induces endothelial autophagy resulting in decreased expression of the tight junction protein ZO-1 leading to breach of the BBB. In this study, we demonstrated that exposure of human brain microvessel endothelial cells (HBMECs) to Tat resulted in induction of autophagy in a dose- and time-dependent manner, with upregulation of BECN1/Beclin 1, ATG5 and MAP1LC3B proteins and a concomitant downregulation of the tight junction protein ZO-1 ultimately leading to increased endothelial cell monolayer paracellular permeability in an
