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

Chemical space exploration has gained significant interest with the increasing availability of building blocks, enabling the creation of ultralarge virtual libraries containing billions or trillions of compounds. However, challenges remain in selecting the most suitable compounds for synthesis, especially in hit expansion. Thompson sampling, a probabilistic search method, has recently been proposed to improve efficiency by operating in reagent space rather than product space. Here, we address some of its limitations by introducing a roulette wheel selection method combined with a thermal cycling approach to balance greedy search and diversity-driven exploration. The effectiveness of this method is demonstrated through 109 queries against twenty distinct 1-million-compound libraries using ROCS.
