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

Drowning involves complex fatal factors, including asphyxiation and electrolyte/osmotic disturbances, as well as hypothermia in cold water. The present study investigated the molecular pathology of pulmonary injury due to drowning, using lung specimens from forensic autopsy cases of drowning (n = 21), acute mechanical asphyxia due to neck compression and smothering (n = 24), and hypothermia (cold exposure, n = 11), as well as those of injury (n = 23), intoxication (n = 13), fire fatality (n = 18), and acute cardiac death (n = 9) for comparison. TaqMan real-time reverse transcription polymerase chain reaction was used to quantify messenger RNA (mRNA) expressions of pulmonary surfactant-associated proteins A and D (SP-A and SP-D), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-10. SP-A and SP-D mRNA levels were lower for drowning, mechanical asphyxiation, fire fatality, and acute cardiac deaths than for hypothermia and injury. TNF-α, IL-1β, and IL-10 mRNA levels were higher for drowning or for drowning and injury than for other groups; there was no significant difference between fire fatality, involving airway injury due to inhalation of hot/irritant gases, and other control groups. These observations suggest characteristic molecular biological patterns of pulmonary injury involving suppression of pulmonary surfactants and activation of early-phase mediators of inflammation in drowning, with high mRNA expression levels of pulmonary surfactants in fatal hypothermia; however, there was no significant difference among these markers in immunohistochemical detection, except for SP-A. These mRNA expressions can be used as markers of pulmonary injury to assist in investigations of the pathophysiology of drowning and fatal hypothermia in combination with other biochemical and biological markers.
