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

Recent studies emphasize the pivotal role of endoplasmic reticulum (ER) stress in Alzheimer's disease (AD), highlighting the need for further investigation into this critical link. In response to ER stress, cells increase reactive oxygen species (ROS) production, leading to heightened oxidative stress. This interplay has sparked interest in antioxidant molecules such as squalene (SQ) as potential therapeutic agents. The primary objective of this study was to examine the impact of SQ on the unfolded protein response (UPR) pathway triggered by ER stress in an in vitro AD model. Herein, molecular docking analysis was performed to evaluate SQ interactions with target proteins, followed by in vitro assays. Human bone marrow-derived mesenchymal stem cells were differentiated into neuronal-like cells and characterized via immunostaining. The cells were then exposed to Aβ
