“Our findings suggest that living NMA seems feasible. The updating frequency may be adapted to the pace of evidence generation. For a similar workload, the clinical question with a faster pace of evidence could be updated every 6 months, whereas those with a slower pace of evidence could be updated once a year.”
We so chose an update frequency of 6 months for our living NMA.
Automated tools for updated living NMA
“Using data from four network meta-analyses,
- We showed that automatic screening can successfully be applied for updating NMA, considerably diminishing the workload without missing any finally included citations.
- We showed that representing citations using word embeddings, a numerical representation of words based on the idea that words with similar meaning occur in similar contexts, improved significantly the prediction of eligible citations when updating NMAs.
The integration of automatic screening for the systematic updating of living NMAs should be considered. It will contribute to the comparative effectiveness research objective and provide a complete and up-to-date overview of the evidence.”
