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

Programmable photonic integrated circuits promise reconfigurable, multifunctional photonic systems, analogous to electronic field programmable gate arrays. However, their scalability is constrained by reliance on volatile thermo-optic tuning, which incurs high power consumption, large footprints, and thermal cross-talk. Chalcogenide phase-change materials (PCMs) offer a superior alternative because of their nonvolatility and substantial optical contrast, yet challenges such as optical loss and bit precision have severely hindered their large-scale adoption. Here, we demonstrate low-loss, multibit control of the PCM Sb
