that's such a vague question

for example, if you have 50 partecipants but only provide the multimedia evidence for 20 of them your study should be thrown out the window

What is preventing someone from having 200 participants, but saying they only had 100 participants, and then only providing evidence for 100 participants?

You have to declare the study population before you request the next round of funding. Thereby fixing the problem.

[CrampusDestrus]

The researchers will have to have gone through some kind of third party agency to get the partecipants. This agency should be queried to see the number they report

Nothing. Pfizer did this, albeit wasn't 50% of the enrollment.

"But we have 20, the other 30 volunteers were removed by unrelated reasons" (and it is common to exclude volunteers from experiments)

[jonlucc]

Every clinical trial paper I've read has a discussion of inclusion and exclusion criteria. I think for the trial to be registered, it has to include this information.

[CrampusDestrus]

"unrelated reasons" should not be an acceptable excuse though. either state the reason or it goes into the trash. and if they were private reasons you can still contact them to confirm they left on their own volition and/or they didn't finish the trial without getting into specifics. you only need one lie to suspect the whole thing
