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

Non-structural carbohydrates (NSC) in grassland plants represent the outcome of carbon (C) allocation processes and serve as integrative indicators of plant C status and nutrient balance. However, their responses to different nitrogen (N) addition rates and to the cessation of long-term N addition remain unclear. In a temperate meadow steppe, we conducted a field experiment with six levels of N addition. We compared changes in the NSC pools and its components (soluble sugars, SS; starch, ST) at the community and functional-group levels. Community NSC and ST pools increased with increasing N addition rates, peaking at 20 g N m
