Reporting and dissemination Flashcards
What is a statistical analysis report? what does it include?
A document provided by statisticians with the results of the analyses specified in the SAP
need to specify
* any deviations from the SAP
* additional analyses not specified in the SAP
when is a clinical study report important?
important document in the drug development and regulatory submission process
especially important for drug marketting applications
regardless of whether the trial is completed or the study is terminated prematurely the slinical trial report should be provided to the regulatory agencies
what is a clinical study report
- a detailed description about the trial design, methods,, results and conclusions
- guildlines on this provided by ICH
- many organisations will have there own template
what is the EudraCT?
European clincal trials database
do sponsors need to post the results of clincal trials in the EudraCT?
Yes, this is now mandaroty
important to provide transparancy of medical products in the EU
what are EQUATOR reporting guidlines?
The EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network is an international initiative that promotes the use of reporting guidelines to improve the accuracy, completeness, and transparency of research publications
different reporting guidlines prodided for different types of studies including:
> CONSORT (Consolidated Standards of Reporting Trials) for randomized controlled trials
STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) for observational studies
PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) for systematic reviews and meta-analyses
SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) for clinical trial protocols
CONSORT reporting guidlines
- research on humans, quantitative results, analysis ocmbined with results of previous stieies and a randomised trial
CONSORT reporting guidlines
- research on humans, quantitative results, analysis ocmbined with results of previous stieies and a randomised trial
Example guidlines for reporting results?
> Sequence generation
8a method used to generate sequence generation
8b Type of randomisation, details of any restriction such as
blocking and block size
Allocation concealment
9. Mechanism used to implement random allocation sequence
Implementation
10. Who generated the random allocation, who enrolled
participants, who assigned participants to interventions
Blinding
11a. If done, who was blinded after assignment to
interventions
11b. If relevant, similarity of interventions
for primary and secondary outcomes what should be reported?
effect size along with its precision (CI)
for binary outcomes what should be reported?
Both the absolute and relative effect sizes
what is a way to minimise publication bias and selective reporting?
Register trials in clinical trial registries
how does submitting trials in trial registries combat bias reporting?
> registering a trial on a publis database
requires n to provide detailed desctiption about the design, methodology and outcomes that will be measured
prevents selective rporting - n outline the outcomes they specified before hand, not new ones or just the significant ones
strategires minimising bias in reporting
- Trial Registries
- Submission of protocol, statistical analysis plan
along with manuscript - Reporting guidelines (e.g. CONSORT)
