[EX Q]: Question: Is childhood maltreatment associated with depression but not with hypochondriasis in later life?
Answer: The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.
[EX A]: yes

[EX Q]: Question: Is acinetobacter baumannii infection in prior ICU bed occupants an independent risk factor for subsequent cases of ventilator-associated pneumonia?

[EX Q]: Question: Does the incorporation of prior genomic information necessarily improve the performance of Bayesian linkage methods : an example involving sex-specific recombination and the two-point PPL?
Answer: Incorporating (correct) prior genomic information is not always helpful. We recommend that the PPLSA be used as the standard form of the PPL regardless of the sex-specific recombination rates in the region of the marker in question.
[EX A]:
no
