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 describes the adsorptive property of vitamins on HA and the effect of the HA adsorbed vitamin on the alkaline phosphatase (ALP) activity for effective use as a bone graft substitute. The vitamins used were calciferol (D3), menaquirone (K2) and 25-hydroxycholecalciferol (25(OH)D3). These vitamins were adsorbed on HA at 4, 10, 20, 37 and 50 degrees C. The adsorption amount was constant below 20 degrees C, and decreased as the incubation temperature increased over 20 degrees C. The order of the adsorption amount was: 25(OH)D3 > K2 > D3. The HA adsorbed vitamins (HA/D3, HA/25(OH)D3 and HA/K2) were suspended in physiological saline for 48 h for the release test. The release ratio of all vitamins increased with incubation time. The order of the release ratio was: 25(OH)D3 > K2 > D3, which was proportional to that of the adsorption amount. The ALP activity of MC3T3-E1 osteoblast-like cells on HA, HA/D3, HA/25(OH)D3 and HA/K2 was also investigated. The ALP activity was higher on HA/25(OH)D3 than on any other samples. However, HA/K2 and HA/D3 showed similar ALP activity to HA.
