Hence, in column 2, we replicate our original OLS specification on the sample of second-decadal changes, with very similar results.
To address the potential criticism that our criteria for the selection of studies (see section 3.1) were to some extent arbitrary, we vary these criteria and re-estimate our preferred specification on the sample of estimates this gives.
Because the frequency with which updated information is collected differs between countries (see Data and data acquisition, and Database conception), many of the key fields are related to the specification of the sampling periods, playing an important role as temporal normalization features.
These findings are robust to different specifications of the sample, whether using the ITT-based or the PPA-based approach.
We find significantly positive correlations between individual trade union membership and paid vacation in all pooled OLS specifications and a marginally insignificant estimated coefficient of individual membership in the FE specification of the stayer sample.
(Salt was used to balance certain prerecorded chemistry specifications). Many of the sample bottles had scratches and marks on the inside of the caps, also indicating tampering.
The measure of the arrival cost of labor inspectors is statistically significant in all specifications for the samples of men and women, and the estimates are remarkably stable across models.
When this inequality does not hold, it will be necessary to re-evaluate the specifications of this sample size calculation.
All prevalence and incidence estimates and CIs described above accounted for the complex survey design through incorporation of sampling weights and specification of the site and sampling unit levels of the design, as previously described.
Methodological items were use of the term "randomised" in the study title and specification of the primary outcome, sample size calculation, method of random sequence generation and allocation concealment, who was blinded, and how blinding was achieved.
