Explanation:
The Rosenhan experiment was conducted to evaluate the validity and reliability of psychiatric diagnosis. The experimenters feigned hallucinations to enter psychiatric hospitals and acted normally afterward.
The David Rosenhan study supported the claim that diagnosis of mental illnesses is often influenced by context and subjective evaluations.
Psychiatrists examined Rosenhan and others. They diagnosed them as mentally ill. As a result, Rosenhan concluded that it is not possible to distinguish between the sane and the insane in psychiatric hospitals.
Option B. is correct
In the intervention group, 212 women (5.7 per 10,000 person-years) and 176 (4.7 per 10,000 person-years) received an ovarian cancer diagnosis (rate ratio [RR], 1.21; 95% confidence interval [CI], 0.99-1.48).
In the intervention group, there were 118 ovarian cancer-related deaths (3.1 per 10,000 person-years), compared to 100 in the standard care group (mortality RR, 1.18; 95% CI, 0.82-1.71).
1080 of the 3285 women who had false-positive test results underwent surgical follow-up, and 163 of them (15%) had at least one significant consequence.
Except for ovarian, colorectal, and lung cancer, there were 2924 deaths from other causes (76.6 per 10 000 person-years) in the intervention group and 2914 deaths (76.2 per 10 000 person-years)
Simultaneous screening with CA-125 and transvaginal ultrasound in comparison to standard treatment did not lower ovarian cancer mortality among women in the general US population. Complications were linked to diagnostic examination after a false-positive screening test result.
