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 menisci are first seen as triangular aggregations of cells in the 20-day rabbit fetus. At 25-days, a matrix that contains types I, III and V collagens has formed. These collagens are also found in the 1-week neonatal meniscus, but by 3 weeks, type II collagen is present in some regions. By 12 to 14 weeks, typically cartilaginous areas with large cells in lacunae are found and by 2 years, these occupy the central regions of the inner two-thirds of the meniscus. The surface layers of the meniscus contain predominantly type I collagen. From 12 to 14 weeks onwards, there is little overlap between the regions with types I or II collagens, that is, these are discrete regions of type I-containing fibrocartilage and type II-containing cartilage. Types III and V collagens are found throughout the menisci, particularly in the pericellular regions. All the cells in the fetal and early neonatal menisci express the mRNA for type I collagen. At 3 weeks postnatal, cells that express type I collagen mRNA are found throughout the meniscus, but type II collagen mRNA is expressed only in the regions of developing cartilage. At 12- to 14-weeks, only type II collagen mRNA is expressed, except at the periphery next to the ligament where a few cells still express type I collagen mRNA. Rabbit menisci, therefore, undergo profound changes in their content and arrangement of collagens during postnatal development.
