Nitrogen status exerts dynamic control over phosphorus sensing and acquisition via PSR1 in colimited marine diatoms.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Nutrient availability controls phytoplankton growth in aquatic ecosystems globally. Phytoplankton frequently experience a limiting supply of multiple nutrients simultaneously (colimitation). Ocean warming is predicted to exacerbate marine nutrient limitation. Yet, how phytoplankton adapt their physiology and regulate responses to colimitation is poorly understood. Here, we show that when the crucial macronutrients nitrogen (N) and phosphorus (P) colimit growth of globally abundant phytoplankton, the diatoms, cellular resources are diverted to prioritize N uptake over P sensing and acquisition. Regulatory mechanisms for responding to fluctuating P supply, including Phosphate Starvation Response 1 (PSR1) and P-resupply sensing via Ca
