This article describes a very sad problem. If a child actually is autistic, the earlier the child is diagnosed, the better. There are now therapies and interventions that can hugely improve the lives of autistic people (and the people who love them).
But the earlier a child is tested, the higher the probability of false positives, of diagnosing autism that isn't there.
Controlling for demographic factors such as age, race, education and household income, researchers who analyzed records of more than 730,000 cancer patients found that married patients did significantly better than single people. They lived longer, received better treatment and were more likely to be diagnosed before metastatic cancers developed.
It didn’t matter whether the unmarried patients were lifelong singles, divorced, widowed or separated. All did worse than demographically similar married patients.
I'd suspect a selection effect also plays a role. But, presumably, the comparison to widowed folks controls for that.
"A Stanford dropout is bidding to make tests more accurate, less painful—and at a fraction of the current price."
Bring it on!
Guess. Go ahead, guess.
And then guess what percentage of cancer in Americans is caused by contamination and pollution.
