Heilsfrágreiðingar: hvat evidensgrundarlagið sær út
12 útgávur, 0 av teimum royndir og 8 samansetingar. Hesin síða lýsir formið á tí litteraturinum heldur enn at samanfatta niðurstøðurnar.
Hvat hetta litteratur er gjort av
Samansetingin er á odda fyri primera litteraturinum her — yvirlit og meta-analyser, ið byggja á eitt modest antal av undirliggjandi studium. Beina tryggar niðurstøður við varsemi, sum sample størrelsen krevur.
Skilnaðurin, sum hevur mest at siga, er millum samanseting og primær rannsókn. Ein meta-analyse samlar royndir og er nærmasta tingið til ein avgreiddan svar, sum ein øki framleiðir. Ein narrativt yvirlit er ein bólkur lesing av sama materialinum og kann vera valfrítt uttan at vera óheiðarlegt. At telja tey saman, sum flestu tilvísingar telja, skýrir júst tað, tú vilt vita.
Hvussu hesa síðu er bygda
Alt ovanfyri er útreiknað út frá tilvísingunum, sum henda síða høvdi frá PubMed og Crossref, ikki skrivað við hond. Tá vikuliga høvdið finnur eitt nýtt papir um hetta evnið, broytast hesi tal og karakteriseringen broytist við teimum. Tað er punktið: ein hand-skrivað áheitan um hvussu sterk eitt evidensgrundlag er byrjar at decay dagin tað er skrivað.
Publikationartypur er tikin sum keldan skrásetur tað. Tað er ófullkomið — tímar merkja ósamstøtt, og eitt papir indexerað sum ein "yvirlit" kann vera eitt systematiskt eitt — so viðger bólkarnar sum umleið. Tey eru nóg væl at greina ein royndarlitteratur frá einum viðmerkingarlitteratur, sum er skilnaðurin, sum hevur mest at siga.
