Detaljerad beskrivning
Patient Registries: A convenient consecutive sampling was used to recruit participants from outpatients in department of rheumatism of PUMCH. Prior to their enrollment in the study, all patients gave written, informed consent. To minimize subject non-response or rejection, the investigators inform patients the benefits and risks, and feedback them all physical examination results for free in the recruit period.
Randomization: A randomization will be used to allocate patients into Lipid-lowering treatment group and control group.
Blind: A trained ultrasonographer who assessed carotid intima media thickness (CIMT) (at baseline and 12 months) will be blinded to all clinical and treatment information.
Statistical analysis: The characteristics of the study sample were summarized using descriptive statistics with dichotomous or ordinal data presented as percentages and continuous data as means, standard deviations, and medians, interquartile range. Differences of progression rate of atherosclerosis between intervention group and control group were assessed with either the t test or the non-parametric Wilcoxon test. A multivariable linear regression model will be used to evaluate the relationship between the progression of CIMT and intervention after controlling for confounding factors. Statistical significance was defined as a 2-tailed P value less than 0.05. All calculations were performed using SAS version 9.3.
Quality Control and Data Management: Two doctors (not the main investigator) who come from department of cardiology with the experiences of clinical trial and a data manager will be serving as Data and Safety Monitor. A monthly meeting will be set up for investigators and monitors. The monitors need to review the study protocol and set Data Safety Management plan before recruitment. Then, they need to review rates of recruitment, adherence, follow-up conditions and assess the efficacy and harm during the study. If Monitors find that the simvastatin-ezetimibe combination therapy is causing severe adverse event, then a detailed record is needed. Monitors need to inform the main investigator within 3 hours and to inform state China Food and Drug Administration within 24 hours. Interim monitoring will focus on data quality, percentage of AE or SAE, and evidence of benefit.
