Oxygen deficits and oxygen delivery kinetics during submaximal intensity exercise in humans after 14 days of head-down tilt-bed rest.
Article in European journal of applied physiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
Beat-by-beat Q(a)O2 and breath-by-breath VO2 were assessed in ten male subjects (24 +/- 3.5 years; 78 +/- 7.7 kg; 182 +/- 5.6 cm) during cycling exercise at 50 W before and after a 14-day period of head-down tilt-bed rest (HDTBR). O2 deficit (DefO2) was calculated as the difference between the volume of O2 that would have been consumed if a steady state had been immediately attained minus that actually taken up during exercise. Q(a)O2 kinetics was described fitting the data with a non-linear mono-exponential model with time delay. Mean response times (MRT) of VO2 and Q(a)O2 kinetics were then calculated. DefO2 and MRT of VO2 response did not change after HDTBR, whereas MRT of Q(a)O2 kinetics increased. The invariance of VO2 kinetics after HDTBR suggests that, although Q(a)O2 response became slower after HDTBR, it did not affect the kinetics of peripheral gas exchange, which probably remained under the control of local muscular mechanisms.
