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

backgroundWe aimed to investigate whether neonatal hypoxic-ischemic (HI) brain injury induces inflammatory lung damage.

methodsThus, hypoxic (HYP, FiO2 10% for 30 min), ischemic (ISC, bilateral carotid flow interruption for 30 min), or HI event was performed in 1-2-d-old piglets. Dynamic compliance (Cdyn), oxygenation index (OI), and extravascular lung water (EVLW) were monitored for 6 h. Then, histologic damage was assessed in brain and lung (lung injury severity score). Total protein content (TPC) was determined in broncoalveolar lavage fluid (BALF), and IL-1β concentration was measured in lung and brain tissues and blood.

resultsPiglets without hypoxia or ischemia served as controls (SHM). HI-induced brain damage was associated with decreased Cdyn, increased OI and EVLW, and histologic lung damage (interstitial leukocyte infiltration, congestive hyperemia, and interstitial edema). BALF TPC was increased, suggesting inflammatory damage. In agreement, tissue IL-1β concentration increased in the brain and lung, in correspondence with increased IL-1β serum concentration. Neither HYP nor ISC alone led to brain or lung damage.

conclusionHI brain damage in newborn piglets led to inflammatory lung damage, suggesting an additional mechanism accounting for the development of lung dysfunction after neonatal HI encephalopathy.
