FVC

FVC declined by 4.3 ml/year for women who cleaned at home and 7.1 ml/year for women cleaners.

This is all part of a strategy that uses momentum to determine sector rotation and risk management; FVC uses its methodology to evaluate First Trust sector and industry ETFs twice a month, and then rebalances when funds fall out of and climb into the top five rankings.

There is great danger that a sudden drop in FVC can take place between clinical visits — and a drop of as little as 10% from baseline can indicate an imminent major event in progress, and even predict a fatality.

“We have one client,” says Bernstein, “seeking a portable spirometer for home use with the accuracy to identify these small drops in the FVC between clinical visits.”

“FEV1 and FVC both actually increased with moderate and occasional use of marijuana,” says Dr. Mark Pletcher, associate professor of epidemiology and biostatistics at the University of California, San Francisco and the lead author of the study.
