A cross-national randomised trial of alprazolam for chronic panic disorder with agoraphobia was run. Compared with previous trials it had three new features: an exposure therapy contrast group, a six-month treatment-free follow-up, and a low rate of early placebo drop-outs ('non-evaluables'). The dose of alprazolam was high (5 mg/day). The 154 patients had(More)

The purpose of this paper is to answer the question: is there evidence for periods of persistent drought in the vicinity of Zaca Lake, Santa Barbara County, California, and can the mechanisms which drive them be identified?
