A study was conducted to evaluate whether an intensive therapy program reduces the risk of developing retinopathy in patients with diabetes. 2100 diabetes patients aged 13- 39 were enrolled in the two-year study, 1063 patients were randomly assigned to the intensive therapy group (intervention group), and 1037 patients were randomly assigned to standard therapy group (control group). This was a two-year study. In year 1, 32 subjects in the intensive therapy group developed retinopathy, and 43 subjects were withdrawn or lost to follow-up. 97 subjects in the standard therapy group developed retinopathy, and 38 were withdrawn or lost to follow-up. In year 2, 26 subjects in the intensive therapy group developed retinopathy, and 30 subjects were withdrawn or lost to follow-up. 89 subjects in the standard therapy group developed retinopathy, and 33 were withdrawn or lost to follow-up 1. Calculate the incidence rate (per 1,000) for the two-year period for each therapy group. Assume losses took place and cases were diagnosed at the midpoint of the period in which they occurred. 2.Calculate and interpret the rate ratio (RR). 3. A Calculate and interpret the percent rate reduction (PRR).

The Physicians' Health Study was a randomized, double-blind, placebo-controlled trial of 22,071 apparently healthy male physicians. Subjects were randomized into two groups: one group took a buffered aspirin every other day and the other was given a placebo. The average follow-up during the aspirin component of the trial was 60.2 months. Baseline cardiovascular risk factors and adherence to therapy during the trial were assessed by questionnaire. Cardiovascular outcomes were reported by questionnaire and confirmed by record review by an Endpoints Committee. Among those taking the aspirin, 104 heart attacks (with five deaths) occurred compared to 189 heart attacks 18 of them fatal among those taking the placebo. The study was terminated early, due principally to a 44% reduction in the risk of a first myocardial infarction (MI). Which of the following are NOT a reason(s) to use a placebo in this trial? Select all that apply. To ensure the ethical review board will approve the…

Plasma IL-12, IL-17, IL-18 and IL-4 concentrations of 36 Systemic Lupus Erythematosus (SLE) patients were determined. Eighteen sex- and age-matched control subjects were included. The cytokine concentrations were determined by enzyme linked immunosorbent assay. The mean duration of the diagnosis of SLE at the time when patients were evaluated for this study was 5.9-6.8 years. The results are shown in Table 1. Table 1 Mean ±s.d.
