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

objectiveTo explore the acute effects of inhaled nitric oxide (iNO) on oxygenation, respiratory rate, and CO2 levels in spontaneously breathing preterm infants treated with nasal continuous positive airway pressure (nCPAP) for moderate respiratory distress syndrome (RDS). DESIGN AND

settingRandomized, prospective, double-blind, cross-over study in the neonatal intensive care units of a university hospital. PATIENTS: 15 infants treated for RDS, with a median gestational age of 32 weeks (27-36), birth weight 1940 g (1100-4125), and postnatal age at the beginning of study 23 h (3-91). nCPAP pressure was kept constant at 4.3 cmH2O (3.4-5.1).

interventionsWe examined effects on gas exchange and vital signs during a 30-min exposure to 10 ppm iNO or placebo gas (nitrogen).

resultsBefore administering test gases the baseline arterial to alveolar oxygen tension ratio (aAPO2) was 0.19+/-0.06. aAPO2 remained unchanged during placebo but increased to 0.22+/-0.05 (+20%) during iNO exposure. Respiratory rate and arterial carbon dioxide tension remained unchanged, as did heart rate, blood pressure, and methemoglobin. Follow-up at 30 days of age showed no deaths, delayed morbidity, or need for supplemental oxygen.

conclusionsAdding 10 ppm nitric oxide to nasal CPAP treatment in preterm infants suffering from RDS results in a moderate but statistically significant improvement in oxygenation, with no effect on respiratory drive or systemic circulatory parameters.
