Name
cent_obs_ratio
Label
Ratio of the number of central apneas with no oxygen desaturation threshold used and with or without arousal to the number of obstructive apneas with no oxygen desaturation threshold used and with or without arousal from type I polysomnography
Calculation
cent_obs_ratio = (carbp + carop + canbp + canop) / (oarbp + oarop + oanbp + oanop)
Type
numeric
