Regressions all include additional controls for state marriage rates and age-adjusted state death rates.
It is possible that the problem of differential measurement error may be reduced by including additional variables as controls in the regression model.
We tried to address some of these issues by including additional community-level controls, but this is a limitation of our study that needs to be more carefully investigated by further research.
In the end, the reviewers agreed that the paper would merit publication in a high impact journal such as eLife by including additional experiments and controls that would significantly strengthen the main conclusions, even if further mechanistic insight was not provided.
Second, we included additional control variables.
The effects of additional potential confounders (other than the matching criteria, controlled for by design) were examined by including additional regression terms into the logistic regression models.
The effects of potential confounders, other than matching criteria, which are controlled for by design, were examined by including additional regression terms into the logistic regression models.
The effects of potential confounders (additionally to the matching criteria, controlled for by design) were examined by including additional terms into the logistic regression models.
The effects of additional potential confounders (other than the matching criteria, which were controlled by study design) were examined by including additional regression terms into the logistic regression models.
In summary, by including these additional controls we confirm our results for the variables that exhibited a more robust association with earnings in our main analysis.
