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

Chloroplast-stealing (a.k.a., "kleptoplastidic") plankton transiently obtain and integrate prey metabolic machinery into their own cells. To do so, they must address a series of challenges, including physical localization of acquired machinery, metabolic integration of organelles and their products, and maintenance of machinery. Here, we study this transient integration in the marine ciliate Mesodinium chamaeleon by pulse feeding the ciliate with cryptophyte algal prey (Storeatula major) and then tracking changes in ciliate cellular ultrastructure, physiology (growth and photosynthesis), and gene expression over time. We demonstrate a predictable series of changes, from the reconfiguration of metabolic activity fueled by recent ingestion, to a period of rapid growth, to a reduction in physiological performance as prey organelle number and functionality become limiting. Because M. chamaeleon also steals transcriptionally active prey nuclei, gene expression is a complex milieu of host and cryptophyte expression, with much of prey metabolism apparently intact in the new host, albeit at low levels. Collectively, our results highlight the holistic orchestration of stolen organelles to produce rapid-yet transient-growth in a new host.
