In Sudy A, a novel MRI technology is evaluated as a screening tool for ovarian cancer. The authors find that the mean survival time is 4 years in the control group and 10 years in the MRI-screened group. In Study B, cognitive behavioral therapy CBT and a novel antidepressant are used to treat patients with comorbid pancreatic cancer and major depression. Patients receiving the new drug are told that they are expected to have quick resolution of their depression, while those who do not receive the drug are not told anything about their prognosis. Which of the following describes the likely type of bias in Study A and Study B?? A: Lead time bias; Pygmalion effect, B: Lead time bias; Golem effect, C: Latency bias; Pygmalion effect, D: Latency Bias; Golem effect, E: Confounding; Golem effect,  <response>: This is a question about identifying types of bias in two medical studies. For Study A, the use of a novel MRI technology as a screening tool results in longer mean survival time compared to the control group. This suggests lead time bias, where earlier diagnosis from the screening test makes it appear that patients live longer, when it may just reflect earlier diagnosis rather than an actual increase in lifespan.For Study B, patients receiving a new antidepressant drug are told they should expect quick resolution of depression, while the control group is not given any expectations. This introduces the Pygmalion effect or self-fulfilling prophecy bias, where high expectations influence outcomes. Telling only one group they will improve faster can lead to actual faster improvement.A: Lead time bias; Pygmalion effect
