Zebra is the American medical slang for arriving at an exotic medical diagnosis when a more commonplace explanation is more likely.[1] It is shorthand for the aphorism coined in the late 1940s by Dr. Theodore Woodward, professor at the University of Maryland School of Medicine, who instructed his medical interns: “When you hear hoofbeats, think of horses not zebras”.[2] Since horses are common in Maryland while zebras are relatively rare, logically one could confidently guess that an animal making hoofbeats is probably a horse. By 1960, the aphorism was widely known in medical circles.[3]

September 15, 2016QT:{{”
To understand how this peculiar situation can come about, suppose you wanted to get from Atlanta to Cincinnati on February 6th. Delta is the only airline that flies direct between these cities, and this week the lowest one-way fare it was offering for that date was $251. However, Delta was also offering flights from Atlanta to Dallas with a stop in Cincinnati for just $197. Why? Because two other airlines also fly direct from Atlanta to Dallas, so price competition on that route is especially fierce. However, there is little to stop those wanting to go from Atlanta to Cincinnati from reserving an
Atlanta-Cincinnati-Dallas trip for $197 and simply ending their journey at the “hidden city” in the middle of their booking, saving $54.

The overview showed a 15% significant relative reduction in breast cancer mortality due to invitation to mammography screening. Heterogeneity in age, trial time, attendance rates, and length of screening intervals may have contributed to the variation in effect between the trials.

Barry James Marshall, AC,[1] FRACP, FRS,[3] FAA (born 30 September 1951) is an Australian physician, Nobel Prize laureate in Physiology or Medicine, and Professor of Clinical Microbiology at the University of Western Australia. Marshall and Robin Warrenshowed that the bacterium Helicobacter pylori (H. pylori) is the cause of most peptic ulcers, reversing decades of medical doctrine holding that ulcers were caused by stress, spicy foods, and too much acid. This discovery has allowed for a breakthrough in understanding a causative link between Helicobacter pylori infection and stomach cancer.
