Write answer in between .Q:A study is conducted to investigate the relationship between the development of type 2 diabetes mellitus and the use of atypical antipsychotic medications in patients with schizophrenia. 300 patients who received the atypical antipsychotic clozapine and 300 patients who received the typical antipsychotic haloperidol in long-acting injectable form were followed for 2 years. At the end of the observation period, the incidence of type 2 diabetes mellitus was compared between the two groups. Receipt of clozapine was found to be associated with an increased risk of diabetes mellitus relative to haloperidol RR 1.43, 95 p0.01.Developed type 2 diabetes mellitus Did not develop type 2 diabetes mellitusClozapine 30 270Haloperidol 21 279Based on these results, what proportion of patients receiving clozapine would not have been diagnosed with type 2 diabetes mellitus if they had been taking a typical antipsychotic?? A: 33.3, B: 0.3, C: 0.03, D: 1.48, E: 0.43,  <response>: This is a question about calculating the attributable risk of developing type 2 diabetes mellitus with clozapine compared to haloperidol. The relative risk of diabetes with clozapine is 1.43 compared to haloperidol. To calculate the attributable risk, we need to know the incidence of diabetes in the clozapine group 30300 10 and the incidence in the haloperidol group 21300 7. The attributable risk is the difference between the incidence in the exposed group clozapine and the incidence in the unexposed group haloperidol, which is 10 - 7 3. This 3 represents the proportion of patients on clozapine who developed diabetes due to clozapine exposure rather than other factors. So the proportion of patients on clozapine who would not have developed diabetes if given haloperidol instead is 3.C: 0.03
