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

Reliable neural recording on densely hair-covered scalp remains challenging due to the incompatibility between efficient hair penetration, conformal skin contact, and low-impedance electrical interfacing. Here, we report a claw-shaped dry electrode that integrates thermoresponsive phase-transition networks for reversible stiffness switching, with temperature-invariant conductivity enabled by crystallization-induced confinement, achieving comfortable, low-impedance neural interfacing on densely hair-covered scalps. The electrode comprises a bottlebrush polymer/multi-walled carbon nanotubes (MWCNTs) composite, in which crystallizable alkyl side chains act as switching units, enabling rigid hair penetration at ambient conditions and compliant, adhesive scalp interfacing at skin temperature. Importantly, side-chain crystallization imposes spatial confinement on MWCNTs, enabling efficient percolated networks with an ultralow percolation threshold (0.47 wt.%) and high electrical conductivity (1.8 S m
