Je was op zoek naar: allocation concealment method (Engels - Italiaans)

in the most recent meta-analysis from the cochrane group in 2005, the results are positive when a glucosamine-containing medicinal product was used, positive for placebo-controlled studies in general and negative when the studies with adequate allocation concealment are retained.
nella più recente metanalisi del gruppo cochrane condotta nel 2005, i risultati sono positivi quando viene utilizzato un medicinale contenente glucosamina, positivi negli studi controllati con placebo in generale e negativi se si considerano gli studi con un adeguato occultamento del gruppo di assegnazione del trattamento.

we assessed included studies for risks of selection bias (method of random sequence generation and allocation concealment), bias due to an absence of blinding (taking into account both performance and detection bias in a single domain), attrition bias (levels and reporting of loss to follow-up), and any other threats to study validity, using the cochrane 'risk of bias' tool (higgins 2011). for each new study in this update, two review authors (of jhb, jlb, nl, sh) independently assessed each study for each domain, in accordance with 'risk of bias' guidance developed by cochrane tobacco addiction to assess smoking cessation studies. where there was any disagreement on the assessment, it was resolved through discussion with a third review author.
