This is (in chart form) what I had suggested previously.  It can be changed to a paragraph. 
 1996   	 US 	 Review US Institute of Medicine (IOM) [23] 	 This review of existing studies concluded there was not sufficient evidence for an association of silicone gel- or saline-filled breast implants with defined connective tissue disease. 

 2000 	 US 	 Review request of a United States District Court[24] 	 This review found "no evidence of an association between...silicone-gel-filled breast implants specifically, and any of the individual CTDs, all definite CTDs combined, or other autoimmune or rheumatic conditions." However, there was "discordance among studies in reports of arthralgias, lymphadenopathy, myalgias, sicca symptoms, skin changes, and stiffness." 

 2001 	 Great Britain 	 UK Independent Review Group 	 Another review of previous studies also found no evidence of an association with an abnormal immune response or connective tissue diseases. However, the report also stated that the question of whether siloxane polymers cause inflammatory reactions that directly provoke immune responses to the recipient's own tissues is unresolved. [2] The study was funded by Dow Corning. 

 2001 	 Australia 	 Retrospective cohort (458 vs other plastic surgery) [25] 	 For diseases that occurred after surgery, there was no difference between the two groups in the incidence in reporting of systemic sclerosis, SLE, or rheumatoid arthritis. However, axillary adenopathy and low titre positive antinuclear antibody (ANA) occurred with a significantly greater frequency in the exposed cohort. 

 2001 	 Sweden 	 Retrospective cohort (2376 vs 3470 breast reduction)[26] 	 The study reported that there was no identifiable increase in well-defined connective tissue diseases. However, women with cosmetic breast implants continue to report specific as well as nonspecific physical and psychological symptoms after receiving their implants. This study was funded in part by Dow Corning. 

 2003 (update) 	 Spain 	 STOA Report to the European Parliament Petitions Committee, 2000 	 This review of existing literature stated that there "does not appear to be clear evidence of increased mortality or specific major diseases from silicone breast implants, but there is still a need for further research, particularly regarding some findings that indicate an apparent increased risk for brain and respiratory cancer, as well as suicide."[3] 

 2004 	 Denmark 	 Followup (2761 vs breast reduction & general population) [27] 	 Found no differences between the implant and breast reduction surgery cohorts in the incidence of any CTD. This study was funded by Dow Corning and the Danish Cancer Registry.
