All errors and missing values are reported in a log file.
Errors and missing values were reported to the contributors and investigators for correction or confirmation.

Not all categories shown for most variables, missing values not reported In Figure 1, mean z-values for BISF-W subscores and the total score are shown by study group with 95% CI, restricted to women with partners for better comparability.
With respect to the study quality assessment, the number of missing values was not reported in 55% of the studies, and no confounding factors were taken into account in around 15% of the studies.
To allow for analysis on participants without symptomatic CAD, this sub-group (n = 16) was excluded in further analyses along with participants unsure of diagnosis and missing values on self reported CAD (n = 21).
Missing values are only reported for variables with more than 25% missing data.
For each variable (continuous or categorical), the percentage of missing values will be reported.
Missing values rates were reported in 22% (n = 25) of studies.
