Neutrophilic Alveolitis and High Serum Pro-Brain Natriuretic Peptide Level may be Indicators of Pulmonary Functional Impairment in Connective Tissue Disorders.
Article in Archives of rheumatology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis study aims to assess the role of several diagnostic tests and tools, immune markers, and the association between serum pro-brain natriuretic peptide levels and other parameters in patients with collagen tissue disorders with pulmonary involvement. PATIENTS AND
methodsIn this prospective study, 62 patients (17 males, 45 females; mean age 58.1±13.6 years; range 24 to 87 years) with pulmonary involvement of connective tissue disorders were evaluated using several functional parameters (six-minute walking test, serum pro-brain natriuretic peptide, echocardiographic measurement of the pulmonary pressure, respiratory functional parameters, and blood pressure measurement), bronchoalveolar lavage differential cytology and/or flow cytometric analysis.
resultsDuration of disease was 7.6 years. Diagnoses included rheumatoid arthritis (38.7%), scleroderma (38.7%), primary Sjögren's syndrome (16.1%), mixed collagen tissue disorder (4.8%), and systemic lupus erythematosus (1.6%). Pulmonary hypertension was present in 38.7% of the patients with the highest incidence of rheumatoid arthritis showing reduced respiratory functions, partial oxygen pressure, and six-minute walk distance, as well as increased serum pro-brain natriuretic peptide and neutrophilic alveolitis.
conclusionHigh serum pro-brain natriuretic peptide levels and neutrophilic alveolitis may provide diagnostic clues for a possible diagnosis of pulmonary hypertension and impaired respiratory functions.
