cell or not).3,4 Here, we will call this the “Haldane-Anscombe” (HA) correction. . The correction due to Haldane and Anscombe is simply to add 0Since small numbers increase the estimation bias, the Haldane's correction should be always applied. This correction adds 0.5 to A, B C and D to estimate the OR (In OR) .Zero‐cell corrections in random‐effects meta‐analysesSince small numbers increase the estimation bias, the Haldane's correction should be always applied.

This correction adds 0.5 to A, B C and D to estimate the OR (In OR) .
The Haldane correction (ie, modifying observations to a value close to zero, for example, 1.0) was used to facilitate statistical analysis of 2×2 tables that included one .
To have a valid estimate of RR, originated from Haldane , one often recommends to add 0.5 to the counts of events and non-events if some count is zero .
haldane correctionMost meta-analytical software (including RevMan) automatically check for problematic zero counts, and add a fixed value (typically 0.5) to all cells of study results tables where the . Haldane states that for inert gasses, volume in remains equal to volume out, and this can be used for calculating changes in breathing volume out from in or vice .
