The phrase "completeness of outcome data" is grammatically correct and commonly used in written English.
It refers to the extent to which all necessary information about the results of a study or experiment is accurately and thoroughly collected and recorded. One example of using this phrase in a sentence could be: "In order to accurately assess the effectiveness of the new treatment, the researchers emphasized the importance of ensuring the completeness of outcome data from all participants."
The quality of the eligible studies was independently assessed by two researchers (EB, MS) using the Cochrane Risk of Bias tool.34 Criteria included randomisation, sequence generation, allocation concealment, blinding (by outcome), completeness of outcome data, selective outcome reporting and presence of other potential sources of bias (e.g. baseline imbalance or incomplete baseline data).
Completeness of outcome data.
Completeness of outcome data enabled us to accurately describe long-term mortality and ESRD incidence.
Blinding and completeness of outcome data were assessed for each outcome separately.
Sequence generation, allocation concealment, blinding, completeness of outcome data, and absence of selective outcome reporting were also assessed.
We will describe the completeness of outcome data for each outcome, including reasons for attrition and exclusions from the analysis.
We assessed the completeness of primary outcome data by comparing General Register Office for Scotland (GROS) births with the number of first CHSP assessment and 6-8 week review records.
The remaining moderate- [ 11] or low-quality [ 12– 28] observational studies reported different completeness of neonatal outcome data for both twins.
The longitudinal design strengthens study findings, as does the completeness of clinical outcomes data even when patient-reported outcomes were missed.
Six key aspects that influence the quality of an RCT were assessed: sequence generation, allocation concealment, patient blinding, personnel and outcome assessors, management of incomplete outcome data, and completeness of outcome reporting, as well as other potential threats to validity.
The SIGN RCT checklist considered randomization strategy, treatment allocation concealment, blinding, success of randomization, use of intention-to-treat principles and the completeness of the reported outcome data (see Additional file 1A).
