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

This Letter comments on the article by Wang et al. on HybridSP and argues that strong benchmark performance should not be interpreted as direct evidence of robust generalization. While the model is interpretable, computationally efficient, and methodologically valuable, its reported results may be inflated by benchmark-specific coefficient tuning and by comparisons across scoring pipelines with different underlying tasks. We further note that performance drops on bias-reduced and more challenging datasets already suggest limits to transferability. We therefore advocate for stricter validation frameworks to support broader claims regarding generalization in protein-ligand scoring.
