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

Diatoms possess a unique photosynthetic apparatus that adapts to constant, extreme changes in light intensity, enabling efficient light harvesting and photoprotection. Fluorescence spectroscopy studies at cryogenic temperatures can reveal details of the electronic excitation dynamics in these evolutionarily successful organisms. Whole-cell studies are highly valuable since they allow investigation of the photosynthetic machinery rather than separate complexes affected by isolation. In this study, we propose an approach that enables cryogenic fluorescence analysis of photosynthetic processes in the diatom
