Waa maxay mamnuucid buuxda ee milkiilayaasha ey badan, waxay siisaa hurdo habeen oo qumman dadka kale: eyga sariirta. Si kastaba ha ahaatee, cilmi-baaris ayaa muujisay in eyga sariirta ku jira uu siiyo hurdo wanaagsan, gaar ahaan haweenka. Si kastaba ha ahaatee: bisaduhu waxay farageliyaan nasashada wax aan ka yarayn dadka.
Saddex cilmi-baarayaal oo Maraykan ah ayaa daraasad ku sameeyay qanacsanaanta hurdada ee ilaa 1,000 milkiilayaasha xayawaanka. Ka soo qayb galayaasha waxaa ka mid ahaa dad aan guursan iyo dad wada shaqayn ku wada nool.
Cilmi-baaristu waxay muujisay: Eeydu waxay uga fiican yihiin dumarka ragga
Natiijada ugu horreysa ee cilmi-baarayaasha ayaa ah in haweenka, gaar ahaan, ay si fiican u seexdaan haddii eygu uu ag jiifo, oo uusan ahayn lammaanahooda.
Guud ahaan, boqolkiiba 55 dadka la waraystay ayaa sheegay in ay eeygoodii u daayeen inuu sariirta seexdo. Si kastaba ha ahaatee, kaliya 31 boqolkiiba ayaa u oggolaanaya bisaddooda inay koolkooliso habeenkii.
Cilmi-baadhayaashu waxay ogaadeen in eyga oo ah lammaane hurda uu yahay midka ugu welwelka yar. Cilmi baaris lagu sameeyo shaybaarka hurdada ayaa loo baahan yahay si natiijada loo dhigo mid gaar ah.
