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

Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function. In an attempt to address this, we examined blood smears from two previous experiments to determine whether ENS frequency is affected by rearing conditions (acclimation temperature or dissolved oxygen level) and subsequent acute aerobic distress in diploid and triploid brook charr Salvelinus fontinalis (Mitchill 1814). As expected, triploids had a higher ENS frequency than corresponding diploids, but with no biologically significant effect of experimental conditions on ENS frequency in triploids. ENS was too rare to examine the effects of these conditions in diploids.
