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

We demonstrate the first Fourier-domain mode-locked optoelectronic oscillator (FDML OEO) fabricated on the thin-film lithium niobate (TFLN) platform, deploying an electrically tuned ultra-fast frequency-scanning filter, thanks to the high-speed Pockels effect in TFLN. Record-breaking high radiofrequency oscillations up to 65 GHz are achieved, with a phase noise more than 14 dB less at 50 GHz than that of a high-performance commercial signal source at an offset frequency of 10 kHz away from the carrier. A linearly chirped microwave waveform with an unprecedented scanning bandwidth of 30 GHz, corresponding to an impressive chirp rate of 5.7 GHz/μs and a large time-bandwidth product of 159054, is successfully generated by the FDML OEO. These results validate the feasibility of utilizing TFLN to fabricate integrated FDML OEOs capable of delivering ultra-wide scanning bandwidth at chirp rates and frequencies not attainable with any other approaches to date.
