Hmm... En tiedä oliko täällä joissain osioissa rajoituksia/kieltoja tutkimusten linkkailun suhteen, mutta niille jotka englantia lukevat, tää voi olla mielenkiintoinen

The factor most significantly associated with increased melanoma risk was the use of sunscreens. Subjects who often used sunscreens had an increased odds ratio (OR) of 3.47 (95% confidence interval [CI]1.81-6.64) compared with subjects who never used sunscreens (P = 0.001), after adjustment for sex, age and other significant sunlight-related factors. Skin colour and higher numbers of sunbaths were significant protective factors. Subjects with medium skin colour had an adjusted OR of 0.63 (95% CI 0.41-0.99) compared with subjects with light skin colour (P = 0.0022). Subjects who took more than 30 sunbaths per year and subjects who took 20-30 sunbaths per year had, in the absence of sunburn(s), a decreased OR of 0.09 (95% CI 0.02-0.39) and 0.28 (95% CI 0.13-0.64), respectively, compared with subjects who took less than 20 sunbaths per year (P = 0.0002). However, sunbaths had no protective value when they were associated with sunburns.
Tuosta voi yrittää tulkita esim näin... Jos haluat melanooman, älä ota aurinkoa ja aina kun otat, käytä aurinkovoiteita. Jos et halua melanoomaa, ota usein aurinkoa ilman aurinkovoiteita ja varo palamista. Toki olisi hyvä saada dataa myös muista tutkimuksista.
