The study of angiogenesis in early rheumatoid arthritis--clinical, immunohistochemical and immunological correlations.

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
objectiveThe objective of the study was to analyze several immunohistochemical, histological, and morphometrical aspects of angiogenesis in early rheumatoid arthritis synovium. We aimed to identify possible correlations between the histological and immunohistochemical patterns and the serum levels of VEGF, as well as with clinical and biological markers of disease activity.
methods35 patients with early rheumatoid arthritis below 12 months from the onset, naive for DMARDs, underwent clinical standard examination as well as serum determinations for CRP, RF. anti-CCP2 antibodies and VEGF. DAS28 value has been determined for each patient in order to assess the disease activity. We performed biopsy sampling through arthroscopy, the synovium fragments beeing histopathologically processed, in order to elaborate a total histological score. Immunohistochemical analysis has been performed with quantification of synovial VEGF, VEGF-R1 and CD34 expression. Standard and activated microvascular density (sMVD and aMVD) have been evaluated through double immunostaining (CD34/ VEGF-R1).
resultsVEGF and VEGF-R1 have been identified with high prevalence in endothelial cells, in lining and sublining synovial cells, as well as in inflammatory cells. The study focuses on the analysis of aMVD, a valuable parameter, representative for active angiogenesis, which proved to correlate significantly with the serum levels of VEGF, the composite histological score as well as with VEGF-R1 and DAS28.
conclusionThe statistic analysis of the data support VEGF-R1 and aMVD as markers with predictive value regarding activity and progression in early stages of rheumatoid arthritis. The validation of preliminary conclusions oblige to continuous research through extending the study group and inclusion of several others biomarkers involved in synovial angiogenesis.
