 [ta´b'l]
a flat layer or surface.
cohort life table a life table giving the survival data of a cohort of individuals in a clinical study or trial, i.e., the number alive and under observation (not lost to follow-up) at the beginning of each year, the number dying in each year, the number lost to follow-up each year, the conditional probability of survival for each year, and the cumulative probabilities of survival from the beginning of the study to the end of each year.
inner table the inner compact layer of the bones covering the brain.
life table any of various tables describing mortality and survival data for groups of individuals at specific times or over defined intervals; tables may summarize combined mortality experience by age over a brief period or may follow a cohort over time (cohort life table).
outer table the outer compact layer of the bones covering the brain.
tilt table a plinth, equipped with a footboard for support, to which a patient can be strapped for rotation to a nearly upright position; used in cases of spinal cord injury and other neurological disorders to enhance blood circulation to the lower limbs, improve posture, and aid in muscle training and sense of balance.
vitreous table inner table.

life ta·ble

a representation of the probable years of survivorship of a defined population of subjects; given that survivorship is changed by new methods of prevention or treatment, a diachronic study is commonly used, the main interest of which lies in the composite structure of the current population. (In the summarizing technique used to describe the pattern of mortality and survival in a population, survivors to age x are denoted by the symbol lx and the expectation of life at age x is denoted by the symbol x.)

life table

Public health A table that presents the results of a clinical study in which subjects enter and leave the trial at different times; each subject has a well-defined point of entry–onset of treatment and end point–relapse, death or other; all subjects may be evaluated at determined intervals with respect to the expected survival of an idealized person, based on actuarial analysis of census data and mortality rates

life table

life table

a tabulation of deaths occurring in age groups, often with other information; may be a current life table, when all of the animals in a population at one time are surveyed, or a cohort table, when all of the animals born in a particular time span are dealt with as a group.
