Effects of being overweight on ventilatory dynamics of youth at rest and during exercise.
Article in European journal of applied physiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Research on obese adults has shown that their ventilatory dynamics differ from normal weight adults; however, the ventilatory dynamics of obese and non-obese children have never been documented. Thus, the ventilatory responses of 73 overweight youth (BMI >85th percentile) were compared to 73 age, sex and height-matched normal weight youth (BMI <85th percentile), during 15 min of rest and steady-state exercise at 4, 5.6 and 8 kph. Overweight youth had higher oxygen uptakes (VO2 mL/min), ventilation (VE), tidal volume (V (T)), frequency (f (R)), physiological dead air space (V (D)) and V (D)/V (T) ratios than normal weight youth (P < 0.02); however, end-tidal CO(2) (P(ET)CO(2)), VE/VO2 and VE/VCO2 were similar. Inspiratory drive (V (T)/t (i)) was greater for overweight youth at rest and during exercise. The correlation between P(ET)CO(2) and inspiratory drive was significant for the overweight group at 5.6 and 8 kph (r = 0.23-0.44), but not significant for the normal weight youth (r = -0.04 to 0.10). The greater drive, respiratory frequency and physiologic dead air space of overweight youth suggest that their adiposity modifies ventilation dynamics during exercise. However, the modifications appear to meet the metabolic demands of exercise.
