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

Temperature is a key factor influencing coastal carbon pools, yet the effects of warming on dissolved organic carbon (DOC) transformations and associated microbial processes remain poorly understood. Through bioassay experiments across a wide temperature gradient (7.6-35.9 °C), three critical thresholds (15.6, 24.6, and 29.9 °C) are identified that delineate distinct regimes of microbial DOC utilization with contrasting carbon fates. Below 15.6 °C, DOC characterized the most unique molecules, and their transformations are governed by bacteria whose relative abundance decreased with warming; hereafter warming-resistant microbes dominated accompanied by DOC molecular signatures that changed till 24.6 °C. Limited substrate availability constrained microbial remineralization rates in these two stages. Once temperatures surpassed 24.6 °C, thermal-favored microbes prevailed but taxa changed after 29.9 °C, DOC accumulated, and a larger fraction of recalcitrant DOC is retained, thereby enhancing carbon sequestration. Network analysis further revealed complex many-one-many resource-consumer-excretion linkages between bacteria and individual DOC molecules, underscoring the tangled nature of microbial DOC processing. The findings demonstrate that coastal DOC cycling responds to warming in a strongly non-linear, threshold-controlled manner, providing critical insights for predicting the behavior of coastal carbon sinks under ongoing climate change.
