Review / evidence synthesis

What this study tells us

This study reviewed or combined evidence from multiple studies. It can show the overall direction of a field, but its conclusion still depends on the quality and relevance of the studies it included.

Who was studied?

Patients with mild-to-moderate Alzheimer disease

How many?

n=6 RCTs

What happened?

Short-term cognitive and global signals favoured Cerebrolysin; cognitive effect at 6 months was not statistically significant while global change remained significant.

What stops us overclaiming?

Older trials; potential sponsor/author involvement; results differ across cognitive vs global endpoints and from stroke evidence.
