inverse of the variance med.

[fistashka80]

Пожалуйста, помогите перевести предложение:

The pooled effect for each grouping of trials was derived from the point estimate for each separate trial weighted by the inverse of the variance (1/SE2).

Которое встречается в следующем контексте:

Statistical analysis was done using standard software (Stata version 9.0, Stata Corp., College Station, Texas) using the METAN program (17). The pooled effect for each grouping of trials was derived from the point estimate for each separate trial weighted by the inverse of the variance (1/SE2). Heterogeneity was assessed visually using funnel plots, Q (chi-square) statistics, and/or the I2 statistics (18). If trials were homogeneous (p > 0.05), a fixed-effect model was used to calculate pooled effect sizes. .....

да? Вы оптимист... я, например, сколько ни перевожу статистику в протоколах - ничего в ней не понимаю :(
