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

The accelerated accumulation of anthropogenic nitrogen input and nitrogen legacies (NL) is a primary driver for persistently high nitrogen loads in rivers. Understanding the impact of nitrogen inputs and NL on river nitrogen export (RNE) is critical for improving water quality. This study employs the net anthropogenic nitrogen input (NANI) approach and export coefficient model (ECM), coupled with remote sensing data, to analyze nitrogen input dynamics, total nitrogen export (TNE), and NL from 1949 to 2021 in China's Dongjiang River watershed. Results indicate that NANI peaked in 2017 while TNE and NL continued to grow. Over the 73 years, NANI grew rapidly from 1949 to 1992, exhibited fluctuating growth from 1993 to 2021, and reached its maximum value (6743 kg·km
