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 effect of the observation interval on two-dimensional trajectory analysis of motility of individual diatom cells of Navicula sp. was studied by comparing thinned-out observation data. The trajectory of cell movement was visualized accurately even after thinning the data interval. However, the analysis of velocity fluctuations of individual cells was found to be significantly affected by the data interval. Reproducibility of the results was guaranteed by analyzing many independent cells. In addition, comparison between automatic and manual determination of cell positions proved that automatic determination was a reliable process. Our data indicated that two-dimensional trajectory analysis using a computer can be a powerful technique to study diatom locomotion.
