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

Exercise performance declines as patients who have undergone Fontan operation enter adolescence. However, the effect of altitude on functional capacity after Fontan remains inadequately studied. Our aim was to describe exercise performance in a cohort of patients with Fontan physiology living at increased altitude and compare to a normal control group and relate these data to invasively derived hemodynamics. We hypothesized that peak oxygen consumption ([Formula: see text]) would be decreased, in association with elevated mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVRi). Patients were evaluated in a multidisciplinary clinic for patients with Fontan physiology. Evaluation included cardiopulmonary exercise test and cardiac catheterization at predetermined intervals. Descriptive statistics were calculated. Associations of catheterization and exercise testing measures with [Formula: see text] were estimated with Spearman correlation coefficients. One hundred patients with age- and gender-matched controls were included in the analysis. The mean age was 13.3 ± 3.9 years, with mean weight of 47.1 ± 18.4 kg. The mean [Formula: see text] was 29.0 ± 7.8 ml/kg/min, significantly lower than the control group, 40.2 ± 8.4 ml/kg/min (p < 0.0001). There was no statistically significant linear correlation between [Formula: see text] and mPAP or PVRi. We characterized exercise performance in a large cohort with Fontan physiology living at increased altitude and showed a decrease in [Formula: see text] compared to controls. Our data do not support the hypothesis that moderately increased altitude has a detrimental effect on exercise performance, nor is there a substantial link between poor cavopulmonary hemodynamics and exercise in this setting.
