Am II just taking the exponent value of 0.58 and 1.19 and comparing if 1 does or does not fall between those amounts?For exp of 0.58= 1.7860Exp of 1.19= 3.2870
England Journal of Medicine that reports the results of a randomized BACKGROUND Coronavirus disease 2019 (Covid-19) occurs after exposure to severe acute respira tory syndrome coronavirus 2 (SARS-CoV-2). For persons who are exposed, th standard of care is observation and quarantine. Whether hydroxychloroquine ca prevent symptomatic infection after SARS-CoV-2 exposure is unknown. METHODS We conducted a randomized, double-blind, placebo-controlled trial across United States and parts of Canada testing hydroxychloroquine as postexposure pro phylaxis. We enrolled adults who had household or occupational exposure to some one with confirmed Covid-19 at a distance of less than 6 ft for more than 10 minute while wearing neither a face mask nor an eye shield (high-risk exposure) or whil wearing a face mask but no eye shield (moderate-risk exposure). Within 4 day after exposure, we randomly assigned participants to receive either placebo hydroxychloroquine (800 mg once, followed by 600 mg in 6 to 8 hours, then 600 m daily for 4 additional days). The primary outcome was the incidence of either lab ratory-confirmed Covid-19 or illness compatible with Covid-19 within 14 days. There were 821 subjects enrolled in this study. Of the 414 randomized to the treatment (Hydroxychloroquine) arm, 49 (11.8%) developed Covid (or probable Covid) within 14 days of randomization. Of the 407 randomized to the placebo arm, 58 (14.3%) developed Covid (or probable Covid) within 14 days of randomization. In Homework #3, you reported a sample relative risk of treatment failure for the DAJ group compared to the EMS group of 0.83 with a 95% CI of 0.58 to 1.19. RR = 0. 83 (0. 118 / 0 .143) Suppose you plan to perform a chi-square (or two sample z-test, or Fisher's Exact Test) for this study. What is the null hypothesis for this test in terms of the Relative Risk (RR)? a, RR= 1 b. RR not equal to 1 1. 7860 C. RR - 0 d. RR not equal to o 3. 2870 23 Recall from Homework #3, the July 2020 article in the New England Journal of Medicine that reports the results of a randomized trial designed to assess the efficacy of Hydroxychloroquine in preventing Covid-19 Infection in persons exposed to others with Covid-19.
