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
A rare case of a patient with chronic obstructive pulmonary disease who developed secondary anthracofibrosis to biomass exposure, fibrosing mediastinitis due to anthracotic enlarged lymph nodes in the mediastinum, and pulmonary hypertension because of compres- sion of the lymph nodes on the pulmonary arteries is presented. This is a case report of a 71-year-old female patient who has been followed up with chronic obstructive pulmonary disease for 10 years, has no history of smoking, and has been exposed to biomass for many years. The patient, who had been hospitalized in various centers for the last 3 years due to progressive shortness of breath and dry cough, applied to us with dry cough and dyspnea complaints. On echocardiography, systolic pulmonary arterial pressure was found to be 59 mmHg. For the etiology of pulmonary hypertension, dual-energy thoracic computed tomography was performed with the suspicion of chronic thromboembolic pulmonary hypertension. No filling defect compatible with thromboembolism was detected. In right heart catheterization, mean pulmonary artery pressure was 27 mmHg, pulmonary capillary tip pressure was 7 mmHg, and pulmonary vascular resistance was 3.71 woods units. Endobronchial ultrasound was applied to the patient with the preliminary diagnoses of lymphoma, anthracosis, fibrosing mediastinitis, and infection. Widespread anthracosis was observed in all lobes and segments macroscopically. The lymph node in the subcarinal area was interpreted as anthracotic lymph node. Anthracosis is defined as black pigmentation involving the mucosal, and submucosal layers of the tracheobronchial tree and the lung parenchyma. If anthracosis is associated with luminal obliteration and/or mucosal proliferation causing obstruction, it is considered anthracofibrosis. In this case, we saw that secondary anthracofibrosis, fibrosing mediastinitis due to anthracotic enlarged lymph nodes in the mediastinum, and pulmonary hypertension may develop because of compression of the lymph nodes on the pulmonary arteries, and we wanted to draw attention to it was a rare case.
