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

This study examined the relative ease with which three dissimilar mineralized tissues from one individual organ were resorbed by osteoclasts in vitro. Cells released from the long bones of prehatch chicks by agitating fragments of the chopped bones in medium were cultured for 24 hours on slices cut from an Elephas maximus molar so that enamel, dentine, and coronal cementum were present in bands on the surface of the slice. The resultant pits were measured using a video-rate, line-confocal reflection light microscope system. Variations in tissue mineralization were characterized by analysis of digital backscattered electron images. The enamel pits were smaller than the dentine and the cementum pits, but the dentine and cementum pits were not significantly different from each other. The sizes of the pits correlated with the relative mineral densities of the three tissues, showing that the rate of osteoclastic destruction of calcified tissues is inversely proportional to mineral density. This indicates that the initial step in osteoclasis, the removal of the mineral phase, determines the volume removed and is the rate-limiting step.
