### Educational Content: Understanding Therapy Outcomes in Severely Ill Patients**Question:** When more severely ill patients are treated with a particular therapy, which of the following results may occur?**Options:**- **A. Better generalization**- **B. Patient-related outcomes decrease**- **C. Pseudo-randomization**- **D. Confounding by indication****Explanation:**This question addresses the potential outcomes and challenges in treating severely ill patients with specific therapies. Each option represents a different concept that may arise during treatment. Understanding these concepts is crucial for evaluating the effects and efficacy of therapeutic interventions in clinical settings.1. **Better Generalization:** This refers to the ability to apply the results from a study to a broader population. In the context of treating severely ill patients, better generalization might not always be achievable due to variations in individual conditions and responses to therapy.2. **Patient-related Outcomes Decrease:** This implies that the effectiveness or benefits perceived by the patients could diminish, especially if the severity of illness affects treatment response adversely.3. **Pseudo-Randomization:** This occurs when the assignment of patients to different treatment groups is not truly random, potentially leading to biases in the study or treatment outcomes. This can be a significant concern in clinical trials involving severely ill patients.4. **Confounding by Indication:** This happens when the reason for assigning a particular treatment is related to the patient's prognosis or severity of illness, which can confound the results. It's a common issue when interpreting the effectiveness of therapies in observational studies involving severely ill patients. Understanding these outcomes helps in designing better studies and improving therapeutic strategies for severely ill patients.

2. 90 male volunteers are randomly assigned to three different treatment programs designed to produce a weight loss by focusing on either diet, exercise, or the modification of eating behaviour. Weight changes were recorded, to the nearest pound, for all participants who completed the two-month experiment. Positive scores signify a weight drop; negative scores, a weight gain (in kg).

PM Wed Nov 3 Stats Home Insert Draw View 8). Studies have shown that drivers who use cell phones while operating a motor passenger vehicle increase their risk of an accident. To quantify this risk, the New England Journal of Medicine (January 2, 2014) reported on the risk of a crash (or near crash) for both novice and expert drivers when using a cell phone. In a sample of 371 cases of novices using a cell phone while driving, 24 resulted in a crash (or near crash). In a sample of 1,467 cases of experts using a cell phone while driving. 67 resulted in a crash (or near crash). a). Find a 93% confidence interval for p, the true crash risk (probability) for novice drivers, also indicating the ME value. Answer: ME = b). Find a 93% confidence interval for p, the true crash risk (probability) for expert drivers, also indicating the ME value. Answer: гр, ME =
