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

backgroundDrought and nitrogen deposition are the major global change factors that alter forest dynamics by affecting tree growth and physiology. However, the impacts of increased nitrogen availability at pre-drought on trees remains poorly understood, and it remains unclear how these responses are coordinated. In this study, we conducted the fertilization-drought microcosm experiment using a widely distributed evergreen broadleaf tree species seedlings (Schima superba) in southern China. The experiment was conducted at 3 stages. First, four levels of N fertilization treatments (without N fertilization-NF, low N fertilization-LF, moderate N fertilization-MF, high N fertilization-HF) were applied for 60 days. Second, all seedlings were allowed to grow under four levels of N fertilization treatments for another 60 days to ensure that the N was absorbed by seedlings. Third, all seedling were subjected to three levels of sustained drought treatments for further 60 days. Traits related to growth and physiology were monitored.

resultsOur findings indicate that drought alone inhibited the growth and leaf photosynthetic rate of S. superba, while N fertilization alone stimulated the growth and leaf photosynthetic rate. Antecedent N fertilization alleviated the drought limitation on growth, due to the increased leaf photosynthetic rate (A

conclusionsOverall, our findings suggest that increased N fertilization prior to drought can alleviate the negative effects of drought on growth and physiology, which is dependent on the magnitude of N fertilization and drought stress.
