The reviewers will independently assess six domains of bias (sequence generation, allocation concealment, blinding or masks, incomplete data assessment, selective outcome reporting, and other sources of bias).
14 This tool includes six domains: sequence generation, allocation concealment, blinding, incomplete data assessment, selective outcome reporting and other sources of bias.
The risk of bias in included studies will be evaluated according to the six domains: sequence generation, allocation concealment, blinding, incomplete data assessment, selective outcome reporting, other sources of bias.
We extracted data on the following: patient characteristics (including age, sex, indication for parenteral access); intervention characteristics (including description of parenteral routes, use of PPE); trial methods (specifically information for 'Risk of bias' assessment); outcome data.

Researchers dealing with the baseline and outcome data assessment were blinded to the intervention assignments.
However, such a criterion would simply reinforce these agencies' current use of these financially conflicted data in determining risk assessment outcome.
Such WOE evaluation is possible only if the studies under review use the same or similar methods of exposure assessment, outcome ascertainment, data analysis, and reporting of results.
There have been few meta-analyses of other environmental exposures and risk of congenital anomalies (e.g., Nieuwenhuijsen et al. 2009) because of great variability in exposure assessment, outcome ascertainment, data analysis, and result reporting.
Incomplete outcome data (assessments should be made for each main outcome or class of outcomes).
