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
Negative pressure pulmonary edema (NPPE) is a rare, life-threatening, yet rapidly reversible complication of acute upper airway obstruction. We present the case of a 17-year-old healthy male who underwent an emergency appendectomy under general anesthesia. Immediately following extubation, he developed severe respiratory distress and desaturation (SpO₂ 70%) due to presumed glossoptosis and reactive laryngospasm. Despite initial stabilization, he deteriorated in the Post-anesthesia Care Unit, exhibiting hypoxemia and pink frothy sputum. Arterial blood gases confirmed acute respiratory acidosis, while chest radiography revealed diffuse bilateral alveolar opacities. A completely normal point-of-care ultrasound (POCUS) served as a valuable adjunct to effectively rule out cardiogenic edema. The patient was managed conservatively with supplemental oxygen and nebulized bronchodilators, while loop diuretics were deliberately avoided. He showed rapid clinical improvement, weaning to room air within six hours, with complete radiological resolution by the next morning. While NPPE is a recognized complication, the educational novelty of this case lies in highlighting the efficacy of targeted conservative management. It underscores the adjunctive role of POCUS in safely avoiding inappropriate diuresis and emphasizes the paramount need for continuous vigilance following extubation.
