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 ascidian Styela clava is an invasive species that easily colonizes new water areas and has a wide distribution. A previously undescribed typhlosole was discovered in S. clava and studied using histological techniques, transmission electron microscopy and computer microtomography. The typhlosole is a large fold of the dorsal intestinal wall that starts in the lower quarter of the stomach and continues to the rectum. Its shape varies greatly: from a rounded protrusion to a spirally twisted fold. The typhlosole is formed by the intestinal epithelium and a thick connective tissue layer, in which pyloric tubules and blood vessels are extended. The epithelium consists of glandular, ciliated, and nonciliated cells demonstrating apocrine secretion. The typhlosole intensifies the food digestion and absorption of nutrients. The features observed in the typhlosole may contribute to a high digestion efficiency even in low-productive waters, determining the biological success of this species.
