asthma pneumonia risk medical model care training data

Extra medical care made asthma look protective to a computer model

A medical model learned that pneumonia patients with asthma were less likely to die. But these patients often received faster or more intensive care because doctors knew they were at higher risk. The model mistook the result of extra care for evidence that asthma itself was protective.
