GBT1118, a compound that increases the oxygen affinity of hemoglobin, improves survival in murine hypoxic acute lung injury.
Article in Journal of applied physiology (Bethesda, Md. : 1985), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Acute respiratory distress syndrome (ARDS) is characterized by lung inflammation and pulmonary edema, leading to arterial hypoxemia and death if the hypoxemia is severe. Strategies to correct hypoxemia have the potential to improve clinical outcomes in ARDS. The goal of this study was to evaluate the potential of hemoglobin modification as a novel therapy for ARDS-induced hypoxemia. The therapeutic effect of two different doses of GBT1118, a compound that increases the oxygen affinity of hemoglobin, was evaluated in a murine model of acute lung injury induced by intratracheal LPS instillation 24 h before exposure to 5% or 10% hypoxia ( n = 8-15 per group). As expected, administration of GBT1118 to mice significantly increased the oxygen affinity of hemoglobin. Compared with mice receiving vehicle control, mice treated with GBT1118 had significantly lower mortality after LPS + 5% hypoxia (47% with vehicle vs. 22% with low-dose GBT1118, 13% with high-dose GBT1118, P = 0.032 by log rank) and had reduced severity of illness. Mice treated with GBT1118 showed a sustained significant increase in SpO
