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

Selenium (Se) biofortification improves crops' nutritional value, while nano-selenium (nano-Se) offers enhanced bioavailability over traditional Se fertilisers. The quality of tea (Camellia sinensis) depends critically on nitrogen (N) metabolism and amino acid balance, particularly of theanine. This study assessing growth and quality, elucidating molecular mechanisms and evaluating long-term persistence explored the effects of nano-Se on tea through three different experiments. The results showed that nano-Se significantly increased the chlorophyll content, photosynthetic parameters and non-structural carbohydrates, indicating an enhanced photosynthetic capacity. Nitrogen uptake and metabolism were promoted, along with an increased leaf nitrogen content, NO
