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

backgroundNitric oxide (NO) deficiency may occur in mitochondrial disorders (MD) and can contribute to the pathogenesis of the disease. It is difficult and invasive to measure systemic nitric oxide. NO is formed in the lungs and can be detected in expired air. Currently, hand-held fractional exhaled nitric oxide (FeNO) measurement devices are available enabling a fast in-office analysis of this non-invasive test. It was postulated that FeNO levels might be reduced in MD.

methodsSixteen subjects with definite MD by modified Walker criteria (4 to 30 years of age) and sixteen healthy control subjects of similar age, race and body mass index (BMI) underwent measurement of FeNO in accordance with the American Thoracic Society guidelines.

resultsSixteen patient-control pairs were recruited. The median FeNO level was 6.5 ppm (IQR: 4-9.5) and 10.5 ppm (IQR: 8-20.5) in the MD and control groups, respectively. In 13 pairs (81%), the FeNO levels were lower in the MD cases than in the matched controls (p=0.021). Eleven (69%) cases had very low FeNO levels (≤7ppm) compared to only 1 control (p=0.001). All cases with enzymatic deficiencies in complex I had FeNO ≤7ppm.

conclusionsSingle-breath exhaled nitric oxide recordings were decreased in patients with MD. This pilot study suggests that hand-held FeNO measurements could be an attractive non-invasive indicator of MD. In addition, measurement of FeNO could be used as a parameter to monitor therapeutic response in this population.
