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.

2 · The registry

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

backgroundAssessment of the severity and extent of disease activity continues to present challenges for physicians in the treatment of ulcerative colitis. Standard markers that can objectively reflect disease activity are useful for physicians to both evaluate the course of ulcerative colitis and monitor the effectiveness of therapy for any given patient.

aimsWe hypothesize that calcitonin gene-related peptide (CGRP) can reflect the activity and severity of ulcerative colitis and be used as a marker to assess the effectiveness of various therapies.

methodsWe examined the expression levels of CGRP by reverse transcription polymerase chain reaction (RT-PCR) and semi-quantitative immunohistochemisty in mucosal biopsies from 38 patients with UC and 18 controls. Levels of CGRP mRNA and protein expression were compared between patients and controls with the clinical activity index (CAI) and the endoscopic activity index (EAI) for various levels of UC severity.

resultsOur results showed that the levels of CGRP mRNA and protein expression were significantly reduced in UC patients compared to controls. This effect was more pronounced in patients with more severe cases of UC. There is a statistically significant negative correlation between levels of CGRP mRNA expression and CAI/EAI scores. A statistically significant negative correlation was also found between levels of CGRP protein expression and CAI/EAI scores. Overall, high CAI and EAI scores were accompanied by low CGRP mRNA and protein expression levels.

conclusionLevels of CGRP protein and mRNA expression in the colonic mucosa of patients are closely associated with UC severity and corroborate traditional indices used to assess the disease.
