Conclusion
Mo e han hal o he News men ions a e no analyzed because pe iod s udied is e y ecen ,
while olume o in o ma ion abou Co id-19 is high. Scien i ic e idence Py amid (Kowalcyk
and T uluck, 2013; Mu ad e al., 2016) is well e lec ed by he Al me ic A en ion Sco e. A

can be conside ed he lame o scien i ic knowledge. Behind hese wo a e he Sys ema ic

On he o he hand, Sys ema ic e iew a emp s o ga he all a ailable empi ical esea ch by

We can conclude ha al me ic in biomedical esea ch, speci ically in he co id esea ch on ,
