A limitation of this study is the retrospective nature of observing treated patients including a methodically non-avoidable selection bias.
Due to the practical and ethical implications of observing junior doctors treating acutely unwell patients on the wards, high-fidelity simulation was used to observe junior doctors' behaviours.
Similarly, the majority (> 93%) of farmers, who reported that they treated lame sheep within 3 days of observing them lame, either always caught the first lame sheep or the first 2 – 5 lame sheep in the group.
The NNH is the number of patients that should be treated to observe the occurrence of one extra adverse event in the treatment group compared to the control group.
The NNH for steroid injection versus other commonly used treatments was 26 (ie, 26 patients would need to be treated to observe the occurrence of 1 extra adverse event in the injection group) compared to all the comparators, and versus placebo it was 9; however, the confidence intervals were not significant.
To further address this clinical question, the Canadian Trauma Trials Collaborative of the Trauma Association of Canada has initiated a multi-center prospective randomized trial of treating or observing selected mechanically ventilated patients with OPTXs [70].
Third, because a particular common pattern associates with so many distinctive underlying processes, it is a mistake to treat each observed case of that pattern as demanding a match to a particular underlying process.
The present scoring system devised from large cohorts of treated patients observed for a long period.
In fact, for many types of cancer, only a minority of treated patients will observe regression of tumor growth.
An increase in the level of PHD2 in the center of the treated tumors was observed when treating with the higher radiation dose of 8 Gy (P<0.05), or with the ultrasound-stimulated treatments combined with radiation [microbubble (MB +ultrasound-stimulated (US)+2 Gy (P<0.008) or MB +ultrasound-stimulated
