A double-blind randomized controlled trial of N-acetylcysteine (NAC) for the treatment of acute exacerbation of chronic obstructive pulmonary disease.

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
Background: Chronic obstructive pulmonary disease (COPD) is a common respiratory disease with acute exacerbation (AECOPD) being a common sequalae which negatively impact health status, rates of hospitalization and readmission, and disease progression. N-acetylcysteine (NAC) has been studied in COPD in both stable state and acute exacerbations, which has been shown to have small beneficial effects in stable COPD, as well as AECOPD. Yet, there has been lack of study with well-designed protocol to assess the role of NAC in more objective outcomes in AECOPD. Methods: This is a double-blind randomized controlled trial. Patients will be randomized in 1:1 ratio to receive oral NAC at 600 mg twice daily or placebo twice daily with standard of care. Partial pressure of oxygen (PaO Discussion: We hypothesize that NAC use in COPD exacerbation can provide benefits in clinical and laboratory parameters. Trial Registration:
