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

Increasing drought events may impair carbon (C) storage in terrestrial ecosystems, but the impacts of isolated vs. recurrent droughts on soil C and its drivers remain unclear. We studied how isolated drought (66% reduction in growing season precipitation over two years) and recurrent drought (the same reduction applied to plots that had previously experienced a 4-year drought followed by two recovery years) influence shallow soil C and its plant-related drivers in two semi-arid grasslands. Despite a one-third decline in soil moisture under both droughts, the responses of above- and belowground C pools and species richness were limited and inconsistent, and soil C remained stable across years, sites, and treatments. Soil C resistance to these droughts was unrelated to the resistance of above- and belowground C pools in the first year of this study. In the second year, the resistance of aboveground forb C pool and belowground C pool promoted soil C resistance under isolated and recurrent drought, respectively. Relationships were observed only at one site, where soil C resistance increased with greater resistance of aboveground biomass, forb, and belowground C pools under isolated drought but decreased with higher species richness under recurrent drought. Overall, short-term isolated or recurrent drought events may not alter shallow soil C when plant-related C drivers show limited negative responses. However, caution is warranted when extrapolating these results, as soil C changes slowly and its response to drought may differ over time and across grassland types.
