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

backgroundThe unique petrifying spring habitats formed by karst topography in Southern China harbor bryophyte communities dominated by the endemic species Hydrogonium majusculum (C. Muell.), which plays a crucial role in habitat maintenance and tufa deposition. However, the underlying adaptive strategies-specifically how H. majusculum coordinates morphological and physiological responses to adapt to such highly heterogeneous sedimentary dynamics-remain unclear.

resultsWe analyzed the geochemical characteristics and plant functional traits across five typical petrifying spring habitats. Redundancy Analysis (RDA) revealed a distinct asynchrony in trait responses: (1) Oxides indicating allochthonous detrital input (K

conclusionsOur data reveal a specific resource trade-off strategy of H. majusculum in dynamic petrifying spring habitats, which is characterized by physiological priority over morphological growth. Under high physical pressure, the moss sends energy to its enzymatic defense system first. This investment maintains cellular stability. The plant moves resources to carbon assimilation and growth only when local physical stress drops. This study explains how H. majusculum adapts to deposition dynamics. These findings also provide a theoretical basis for the management and protection of petrifying spring habitats.
