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 have developed a complete end-to-end high-throughput protocol for rapid estimation of logP values of peptide molecules. This scheme combines two core technologies: firstly, the "pool and split" high-throughput synthesis technology is used to efficiently prepare peptide samples; secondly, a logP detection method based on ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS) was developed, which relies on high-resolution mass spectrometry to accurately identify hundreds of components in mixed samples. In addition, we innovatively established a linear correlation model between chromatographic capacity factor logK' and logP, which has an excellent correlation (R² = 0.92) and can accelerate fully automated data analysis. Finally, we successfully synthesized and detected mixed samples containing 16, 81, and 256 peptide molecules, with a logP detection rate exceeding 85%. The sample processing capacity of this detection system can exceed 20000 per day, which can significantly accelerate the early screening process of lead molecules in drug development.
