Asymmetric photooxidation of glycerol to hydroxypyruvic acid over Rb-Ir catalytic pairs on poly(heptazine imides).
Article in Nature nanotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
Selective asymmetric oxidation of glycerol (GLY) to hydroxypyruvic acid (HPA) offers an attractive approach for chiral drug synthesis, but this process is highly challenging. Here we develop a photocatalytic method to achieve heterogeneous selective photooxidation of GLY to HPA over rubidium (Rb) and iridium (Ir) catalytic pairs decorated on a poly(heptazine imide) framework. The Rb sites effectively adsorb GLY molecules through the terminal -OH groups, thus inhibiting their oxidation during photoreaction, while the Ir sites enhance the oxygen reduction reaction and the in situ generated surficial oxygen-reduction radicals on Ir can protect the reactive C-centred radical intermediates produced during photooxidation. The spatial arrangement of Rb and Ir sites facilitates hydrogen extraction-an essential rate-determining step for GLY photooxidation-and protects C3 radical intermediates from overoxidation. This photocatalytic system achieves a remarkable productivity for HPA synthesis (~8,000 μmol of HPA per gram of photocatalyst per hour) under visible-light illumination.
