Write answer in between .Q:The division chief of general internal medicine at an academic medical center is interested in reducing 30-day readmissions for diabetic ketoacidosis DKA in elderly patients. Her research team decided to follow 587 patients over the age of 65 who have recently been admitted to the hospital for DKA for a 30-day period. At the end of 30 days, she identified 100 patients who were readmitted to the hospital and examined risk factors associated with readmission. The main results of her study are summarized in the table below.RR 95 CI P-valueEpisodes of DKA in the past 3 years 0.001None Reference121.23 1.041.3634 1.48 1.381.595 2.20 1.832.51Which of the following aspects of the results would support a causal relationship between a history of DKA and 30-day readmission risk for DKA?? A: Low p-value, B: Confidence intervals that do not cross 1.0, C: Case-control study design, D: High odds ratio, E: Dose-response relationship,  <response>: This is a multiple choice question asking about interpreting the results of a cohort study examining the association between prior episodes of diabetic ketoacidosis DKA and 30-day readmission risk for DKA in elderly patients. The key results are presented in a table showing the relative risk and 95 confidence intervals for 1-2, 3-4, and 5 prior DKA episodes compared to none. The relative risks increase in a dose-response manner with increasing number of prior DKA episodes. The p-value is very low, suggesting strong statistical significance. Choice A is incorrect because a low p-value alone does not establish causality, only a strong statistical association. Choice B is incorrect because confidence intervals not crossing 1.0 indicates statistical significance, but does not alone imply causality.Choice C is incorrect because this was a cohort study, not a case-control study.Choice D is incorrect because a high odds ratio does not necessarily imply causality, only a strong association. Choice E is the best answer because the dose-response relationship seen supports a causal relationship between prior DKA episodes and readmission risk. The increasing relative risks with increasing exposures suggests a biological gradient supporting causality.E: Dose-response relationship
