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

INTRODUCTION/

objectivesBehcet's disease (BD) is a systemic and chronic inflammatory vasculitis with unknown etiology. Diagnosis is determined by evaluating several clinical criteria, but the lack of specific laboratory diagnostic markers makes the diagnosis of BD more difficult. Therefore, the aim of this study was to determine the changes in hematological parameters in BD patients to investigate their relationship with BD clinical features.

methodA total of 48 BD patients and 96 healthy controls were included in this study. The severity of each BD patient was associated to a severity score according to the entire spectrum of disease manifestations. Several laboratory tests were assessed, and the difference in their results between BD patients and healthy controls was evaluated. Correlation analysis was performed to reveal the interaction of these parameters.

resultsC-reactive protein (CRP), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), neutrophil count, platelet count, and plateletcrit significantly increased in BD patients compared with healthy controls (P < 0.05). CRP was higher in patients with skin lesions, MCH and MCHC were lower in patients with vascular involvement, and the neutrophil count was higher in patients with skin lesions and genital ulcers. In addition, higher CRP and lower MCH and MCHC were associated with a severe condition. Besides, MCH and MCHC were negatively correlated with the platelet count, plateletcrit, and neutrophil count.

conclusionsThis study revealed that MCH and MCHC are valuable parameters for BD. Their levels help assess the disease severity and indicate the vascular involvement in BD. Key Points • This is the first study reporting MCH and MCHC as important biomarkers in BD. • BD patients with vascular involvement and thrombosis potential have lower levels of MCH and MCHC. • MCH and MCHC are negatively correlated with platelet count, plateletcrit, and neutrophil count. • Lower MCH and MCHC are associated with a severe condition.
