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

introductionThis study investigated the expression of interferon-γ (IFN-γ) and interleukin-4 (IL-4) in the esophageal biopsies from patients with reflux esophagitis (RE) and Barrett's esophagus (BE) and their relationships with endoscopic grading and histologic grading.

methodsNinety individuals were recruited (30 RE, 30 BE, and 30 normal control) and underwent upper gastrointestinal endoscopy with esophageal biopsy. Immunohistochemistry was used to semi-quantitatively detect the expression of IFN-γ and IL-4 in the specimens.

resultsIFN-γ was overexpressed in BE and RE compared with the control (P < 0.01), whereas IL-4 was up-regulated in BE compared with RE and control (P < 0.01). A positive correlation between the level of IFN-γ and the endoscopic grading (r = 0.509, P < 0.01) and histologic grading of RE (r = 0.493, P < 0.01) was observed.

conclusionsTh1 and Th2 immune responses play different roles in the development of RE and BE. Th1 immune response is the major pathway for RE development, whereas both Th1 and Th2 immune responses are implicated in BE pathogenesis. The expression of IFN-γ is associated with the endoscopic and histologic grading of RE.
