LLT: lipid layer thickness. LLT average: average value of LLT during 19.1-second measurement. LLT max: maximum value of LLT during 19.1-second measurement. LLT min: minimum value of LLT during 19.1-second measurement. Blink: number of blinks during 19.1s. Partial blink: number of partial blinks during 19.1s. r: relative coefficient. P: significance. n: number.
