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

Sleep disorders at high altitude are common and well-known for centuries. One symptom of the complex is periodic breathing (PB). PB occurs from a disbalance of the negative feedback loop of ventilation control, and at high altitude, it is increased by a phase shift of 180 degrees between hyperventilation and hypoxia. This paper explains the mechanisms that trigger the problem and discusses whether PB may be of advantage or disadvantage for the person going to high altitude. Up to about 3,000-3,500 m, PB may be of advantage because it stabilizes oxygen saturation at a relatively high level. At higher altitudes, disadvantages predominate because frequent arousals cause total sleep deprivation and mental and physical impairment of the victim. Correct acclimatization and "defensive" altitude profiles are gold standard, which minimize PB and optimizes recreative sleep, although they cannot mask PB completely, especially at extreme altitude.
