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 advancements in nonlinear optics have significantly revolutionized the field of integrated photonics, offering on-chip solutions for a diverse array of cutting-edge applications. The strategic implementation of second-order nonlinear interactions within compact devices not only enhances energy conversion efficiency but also unlocks novel operational paradigms, highlighting their potential for room-temperature longwave infrared detection at the single-photon level. In this study, we present spectral frequency upconversion from the longwave infrared (LWIR) to the near-infrared (NIR) regime, utilizing specifically designed AlGaAs-on-insulator (AlGaAsOI) microresonators. By developing a comprehensive theoretical framework for the
