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

Nanoparticles (NPs) are used in our everyday life, including as drug delivery vehicles. However, the effects of NPs at the cellular level and their impacts on autophagy are poorly understood. Here, we demonstrate that the NP drug delivery vehicle poly(butyl cyanoacrylate) (PBCA) perturbs redox homeostasis in human epithelial cells, and that the degree of redox perturbation dictates divergent effects of PBCA on autophagy. Specifically, PBCA promoted functional autophagy at low concentrations, whereas it inhibited autophagy at high concentrations. Both effects were completely abolished by the antioxidant N-acetyl cysteine (NAC). High concentrations of PBCA inhibited MAP1LC3B/GABARAP lipidation and LC3 flux, and blocked bulk autophagic cargo flux induced by mTOR inhibition. These effects were mimicked by the redox regulator H
