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

Physical unclonable functions (PUFs)-a hardware-based security device using randomness-have evolved from basic integrated circuit designs to advanced systems using diverse materials and mechanisms. However, most PUFs are limited by single-factor challenges and fixed key generation, making them vulnerable to brute-force attacks. A reconfigurable and multidimensional liquid crystal (LC)-based PUF is presented integrated into an organic field-effect transistor (OFET) to address limitations. This system combines optical and electrical PUFs through unique optical fingerprint textures and random molecular alignment of the semiconductive smectic LC material. The PUF can be reconfigured by a simple heating and cooling process, overcoming the limitations of fixed-structure PUFs. Furthermore, this approach enhances security by enabling hierarchical authentication due to the multi-response factors, providing robust solutions for anticounterfeiting and cryptographic applications.
