Macrophage-like synoviocytes display phenotypic polymorphisms in a serum-free tissue-culture medium.
Article in Rheumatology international, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Synovial macrophages play an outstanding role in many rheumatic diseases. However, traditional serum-containing tissue-culture techniques hamper in vitro studies due to fibroblast activation not found in vivo. The objective of this study was to examine dissociated synovial cells in a macrophage-selective, serum-free tissue-culture medium. Osteoarthritis synovial tissue (n=11) was cultured in Iscove's Modified Dulbecco's Medium (IMDM) with 10% fetal bovine serum (FBS) and compared to a serum-free, insulin-supplemented medium. After 9-11 and 19-21 days in vitro, immunohistochemistry was performed for macrophage/lymphocyte markers and cell division. Cytokine profiles were determined by RT-PCR. In serum, cells with a bipolar morphology rapidly proliferated. Respectively, 14.34+/-12.94% and 13.25+/-12.66% expressed CD68 and HLA-DR. These markers further decreased after one passage. In serum-free medium, proliferation was infrequent, and cells with diverse morphologies expressed 83.10+/-6.80% and 55.03+/-6.88% CD68 and HLA-DR respectively. CD14 was rare, and lymphocytes were missing. Both cultures expressed interleukin-6 and interleukin-8. This novel serum-free method permits the culture of distinct CD68/HLA-DR associated phenotypes.
