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

Background: With the recent acceleration of manned space exploration, health care in space has become an important issue. Cardiovascular problems, mainly caused by the microgravity environment in space, include decreased red blood cell volume, myocardial atrophy and aerobic capacity, and reduced orthostatic tolerance after return. However, complete physiological countermeasures have not been established and more research is needed. Methods and Results: A search on PubMed was conducted for English-language articles on cardiovascular changes in space and their countermeasures and post return rehabilitation. Early in space flight, diuresis associated with fluid shifts causes changes in erythrocyte volume, and after prolonged stays, the vestibular and cardiocirculatory systems are induced to show orthostatic intolerance due to decreased blood pressure increasing reflexes, decreased circulating plasma volume, and myocardial atrophy. The main countermeasures include aerobic exercise and strength training in space 6 days a week, for approximately 2 h a day, and a rehabilitation program after return to re-adapt to the Earth's gravitational environment. Conclusions: In the near future, when people with heart disease and the elderly will fly in space, new health management techniques that combine the knowledge accumulated in space flight and cardiac rehabilitation on the ground will be necessary for in-flight countermeasures against cardiovascular changes in space and for post-return rehabilitation.
