1 · What the graph read from 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.

Abstract

introductionTransforming growth factor beta-1 (TGF-β₁) is an important genetic modifier of lung disease severity in cystic fibrosis (CF), yet the mechanism behind this disease association remains unknown. Initial steps in the investigation of the relationship between TGF-β₁ and CF lung disease include determining the most appropriate available biospecimen for TGF-β₁ protein measurement. HYPOTHESIS: In hospitalized pediatric CF patients, plasma TGF-β₁ is increased in association with clinical parameters of lung disease severity.

methodsSerum and plasma were obtained pre- and post-intravenous antibiotic therapy in pediatric CF patients hospitalized for a pulmonary exacerbation. Total TGF-β₁ , measured via ELISA, was compared with markers of lung disease, including airway microbiology, lung function, and response to therapy.

resultsForty CF children were studied, 15 of whom underwent bronchoalveolar lavage (BAL) at the time of admission. Plasma TGF-β₁ positively correlated with BAL fluid (BALF) TGF-β₁ (r=0.59, P<0.05). Admission plasma TGF-β₁ was increased in subjects positive for Pseudomonas aeruginosa (P=0.014) and was inversely associated with diminished lung function (P<0.038) after therapy. Treatment with antibiotics significantly decreased plasma TGF-β(1) (P<0.001). Serum TGF-β₁ was not associated with plasma TGF-β(1) , BALF TGF-β₁, or these clinical parameters of lung disease.

conclusionIn pediatric CF, plasma (but not serum) TGF-β₁ is increased in association with Pseudomonas infection and lung disease, and is reduced in response to therapy. These findings emphasize the importance of optimizing biospecimen selection for future studies investigating the role of TGF-β(1) in CF lung disease.
