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

Mechanical signals are pivotal ingredients in how cells perceive and respond to their microenvironments, and to synthetic biomaterials that mimic them. In spite of increasing interest in mechanobiology, probing the effects of physical cues on cell behavior remains challenging for a cell biology laboratory without experience in fabrication of biocompatible materials. Hydrogels are ideal biomaterials recapitulating the physical cues that natural extracellular matrices (ECM) deliver to cells. Here, protocols are streamlined for the synthesis and functionalization of cell adhesive polyacrylamide-based (PAA-OH) and fully-defined polyethyleneglycol-based (PEG-RGD) hydrogels tuned at various rigidities for mechanobiology experiments, from 0.3 to >10 kPa.  The mechanosignaling properties of these hydrogels are investigated in distinct cell types by monitoring the activation state of YAP/TAZ. By independently modulating substrate stiffness and adhesiveness, it is found that although ECM stiffness represents an overarching mechanical signal, the density of adhesive sites does impact on cellular mechanosignaling at least at intermediate rigidity values, corresponding to normal and pathological states of living tissues. Using these tools, it is found that YAP/TAZ nuclear accumulation occurs when the projected area of the nucleus surpasses a critical threshold of approximatively 150 µm
