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

purposeThe D allele of the insertion/deletion (I/D) polymorphism of a 287-bp sequence in the angiotensin-converting enzyme (ACE) gene has been associated with an increased activity of this enzyme. Its role in susceptibility to acute respiratory distress syndrome (ARDS) has not been well defined. We hypothesized that ACE I/D genotype in pediatrics is associated with ARDS and plasma levels of angiotensin II.

methodsProspective case-control study in patients under 15 years of age from a mixed Chilean population. Sixty patients with ARDS and 60 controls were included. Association between ACE genotype and ARDS was evaluated as the primary outcome; mortality and severe hypoxemia were examined as secondary outcomes. Plasma angiotensin-II concentration was measured by immunoassay at admission.

resultsFrequency of ACE I/D genotype was similar in ARDS and control groups (p = 0.18). In the ARDS group, severe hypoxemia was less frequent in D allele carriers (p < 0.05). Plasma angiotensin-II levels were associated with genotype in the ARDS group, but not controls, being higher in D allele carriers (p = 0.016).

conclusionThese data do not support the association between ACE I/D genotype and ARDS, although severe hypoxemia was less frequent in D allele carriers. ACE I/D polymorphism modified angiotensin-II levels in pediatric ARDS, but its pathogenic role is not well understood and needs to be addressed in future studies.
