Frugal Sampling Strategies for Navigating Complex Reaction Spaces.
Article in Organic process research & development, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
As the complexity of the chemical space continues to grow, innovative strategies are required to enhance screening efficiency. With the main goal of identifying overarching trends, we introduce novel high-throughput experimentation (HTE) sampling strategies that explore broader chemical spaces and only require 25% of the experiments compared to full factorial designs. Our carefully designed quasi-random sampling methods maximize plate layout diversity while preserving practicality for 96-well microtiter plates. The frugal samplings were successfully applied to four challenging metal-catalyzed cross-coupling reactions. The resulting screens retained sufficient information to understand the main tendencies and enable informed decision-making for subsequent optimization activities. In one case study, the method was coupled with a Bayesian optimization workflow to enable cost-effective transformations within the explored chemical space by introducing a cost-penalized yield as an optimization objective.
