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

In cereal seed, there are no symplastic connections between the maternal tissues and the endosperm. In order to facilitate solute transport, both the nucellar projection and its opposite endosperm epithelial cells in wheat caryopsis differentiate into transfer cells. In this paper, we did contrast observation and investigation of wheat endosperm transfer cells (ETC) and nucellar projection transfer cells (NPTC). The experimental results showed that there were some similarities and differences between ETC and NPTC. ETC and NPTC almost developed synchronously. Wall ingrowths of ETC and NPTC formed firstly in the first layer nearest to the endosperm cavity, and formed later in the inner layer further from the endosperm cavity. The mature ETC were mainly three layers and the mature NPTC were mainly four layers. Wall ingrowths of ETC were flange type and wall ingrowths of NPTC were reticulate type. NPTC were not nutrient-storing cells, but the first layer of ETC had aleurone cell features, and the second layer and third layer of ETC accumulated starch granules and protein bodies.
