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

Inflammation of the human intestine causes thickening of the smooth muscle layers, and studies in rats infected with Trichinella spiralis (Tsp) have shown hyperplasia of the intestinal smooth muscle cells (ISMC). We have shown that Tsp-induced inflammation caused a fivefold increase in total protein per ISMC over control, while ISMC from the noninflamed distal ileum also showed a threefold increase. The amount of alpha-smooth muscle (SM) actin per ISMC increased nearly 500% over control by postinfection (PI) day 6. The proportion of alpha-SM actin in the total cellular protein increased 200% by day 6 PI, indicating a higher density of alpha-SM actin in the hypertrophied ISMC. Gamma-SM actin mRNA increased sharply and was matched by an increased fractional content of gamma-SM actin protein. These increases in the smooth muscle-specific actins may affect force production and further demonstrate the plasticity of smooth muscle in the inflamed intestine.
