Penyelidikan perubatan untuk Pameran Sains Oleh Chris Grinter, pada 2 April, 2010 (iStockphoto) I am really at a loss for understanding yet another positive acupuncture study that was as well designed as my 8th grade science fair project. Diberikan, Saya adalah seorang budak sains nerdy, tetapi saya boleh lakukan mabuk kerja yang lebih baik. I think I should conduct a followup study in which I test the efficacy of porcupines tossed at your back. It would certainly be more amusing; and full of just about as much scientific value. Not to mention, porcupines are kinda cute. The real problems with the study: - Unblinded Their x² tests may have resulted in a significant response, but in no imagination of any universe does 15 equal a statistically significant sampling of any population, anywhere. - No negative control. They treated all of their patients with acupuncture or vitamins. Vitamin B complex is a treatment (still a very poorly supported one), and only a positive control. Whose to say smell didn’t naturally improve over the course of the study? The authors can not. So my question is, what can possibly be the motivation for this study? I can imagine how this was dreamt up, around the coloring books one day “Hey Doc Julia, acupuncture sure works huh?” “Why yes it does fellow idiot, let’s create a really crappy study to show just that!”. Take a look at my older acupuncture post for more links and a bit more discussion on why ancient chinese medicine is a waste of money. Of course if you test 15 people you can scrape together a positive result for just about anything. But as you start to introduce larger and more tightly controlled studies the positive effects start to shrink. Ridiculous. And now that I look at it, my 8th grade science fair project was conducted with two sets of controls, blinded, and had a sample size of 18 (antibacterial effectiveness of kitchen cleaners). Terima kasih, I’ll kindly take my position at the University of Cologne Medical Center now. Seperti ini: Seperti Memuat...

Taighde Leighis don Aonach Eolaíochta Ag Chris Grinter, ar an 2 Aibreán, 2010 (iStockphoto) Tá mé i ndáiríre ag caillteanas do thuiscint eile fós Staidéar acupuncture dearfach go raibh chomh deartha go maith le mo thionscadal cothrom eolaíocht 8 grád. Deonaithe, Bhí mé a kid eolaíochta nerdy, ach d'fhéadfadh liom a dhéanamh ar meisce poist níos fearr. I mo thuairimse, ba chóir dom a staidéar follow ina mé tástáil ar an éifeachtúlacht torcán tossed ar do chúl. Bheadh sé a bheith cinnte níos amusing; agus go hiomlán de luach eolaíochta díreach faoi an oiread. Gan trácht ar, Tá torcán kinda gleoite. Na fadhbanna fíor leis an staidéar: - Unblinded Is féidir a n-tástálacha x² bheith mar thoradh ar freagra suntasach, ach in aon samhlaíocht ar bith cruinne dhéanann 15 comhionann le sampláil suntasach go staitistiúil ar bith daonra, áit ar bith. - Aon smacht diúltach. Déileálfar siad go léir a n-othar a bhfuil acupuncture nó vitimíní. Tá Vitimín B casta a chóireáil (fós an-lag tacaíocht), agus gan ach a rialú dearfach. Cé leis a rá nach raibh boladh a fheabhsú go nádúrtha le linn an staidéir? Ní féidir leis na húdair. Mar sin, tá mo cheist, cad is féidir a bheith, b'fhéidir, an spreagadh don staidéar? Is féidir liom a shamhlú conas a bhí sé seo dreamed suas, ar fud na leabhair dathúcháin lá amháin “Hey Doc Julia, acupuncture oibreacha cinnte huh?” “Cén fáth yes a dhéanann sé leathcheann eile, a ligean ar chruthú staidéar i ndáiríre crappy a thaispeáint go díreach!”. Féach ar mo phost acupuncture níos sine le naisc níos mó agus plé beagán níos mó ar leigheas Sínis cén fáth a ársa go bhfuil cur amú airgid. Ar ndóigh, má tá tú tástáil 15 daoine is féidir leat scrape le chéile de thoradh dearfach do díreach faoi rud ar bith. Ach mar a dtosaíonn tú a thabhairt isteach staidéir níos mó agus rialú níos docht tús a chur leis na héifeachtaí dearfacha a Laghdaigh. Ridiculous. Agus anois go bhfuil mé ag féachaint ar air, bhí mo tionscadal cothrom eolaíocht ghrád 8 a rinneadh le dhá thacar de rialuithe, blinded, agus bhí méid na samplaí de 18 (éifeachtacht antibacterial de glantóirí cistine). Go raibh maith agat, Feicfidh mé a ghlacadh cineálta mo sheasamh ag Ollscoil Köln Ionad Leighis anois. Cosúil le seo: Cosúil Ag luchtú ...
