Erdosteine reduces inflammation and time to first exacerbation postdischarge in hospitalized patients with AECOPD.
Trial report in International journal of chronic obstructive pulmonary disease, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
purposeMucolytics can improve disease outcome in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). The objectives of this study were to investigate the effects of erdosteine (ER), a mucolytic agent with antioxidant activity, on systemic inflammation, symptoms, recurrence of exacerbation, and time to first exacerbation postdischarge in hospitalized patients with AECOPD. PATIENTS AND
methodsPatients admitted to hospital with AECOPD were randomized to receive either ER 900 mg daily (n=20) or a matching control (n=20). Treatment was continued for 10 days until discharge. Patients also received standard treatment with steroids, nebulized bronchodilators, and antibiotics as appropriate. Serum C-reactive protein levels, lung function, and breathlessness-cough-sputum scale were measured on hospital admission and thereafter at days 10 and 30 posttreatment. Recurrence of AECOPD-requiring antibiotics and/or oral steroids and time to first exacerbation in the 2 months (days 30 and 60) postdischarge were also assessed.
resultsMean serum C-reactive protein levels were lower in both groups at days 10 and 30, compared with those on admission, with significantly lower levels in the ER group at day 10. Improvements in symptom score and forced expiratory volume in 1 second were greater in the ER than the control group, which reached statistical significance on day 10. ER was associated with a 39% lower risk of exacerbations and a significant delay in time to first exacerbation (log-rank test P=0.009 and 0.075 at days 30 and 60, respectively) compared with controls.
conclusionResults confirm that the addition of ER (900 mg/d) to standard treatment improves outcomes in patients with AECOPD. ER significantly reduced airway inflammation, improved the symptoms of AECOPD, and prolonged time to first exacerbation. The authors suggest ER could be most beneficial in patients with recurring, prolonged, and/or severe exacerbations of COPD.
