The study sample was small, the follow-up period was short, and a pathological diagnosis was not established in half of the patients. If the number of patients and follow-up period had increased, different trends may have emerged in the multivariate analysis that did not show significant ...
Samples of the test substance in the chamber were collected three times using a 25-mm micro-glass filter and a personal sample collector (Model No. Airchek XR 5000, SKC Inc., USA) from the breathing area of the test animals during exposure to the test substance. The weight of the filter...
the mixtures were inoculated by centrifugation into HeLa-229 cells grown on shell vials. After 30 h at 37 °C, the monolayers were fixed and stained with a pool of monoclonal antibodies63. The titer of a sample is the dilution that yielded 50% neutralization relative to the control seru...
A sample size calculations showed that assuming a 35% mortality rate in the control group, 350 patients per group would provide 80% power at a 2-sided level of 0.05 to detect a 10% absolute reduction of mortality in the PC-SV group, based on the potential combination of the effects of ...
How- ever, the study observed a predominance of infections in males, which differs from other studies and may be attributed to sample selection bias [16]. Different respiratory pathogens exhibit varying epide- miological patterns, typically showing seasonal epidemic characteristics influenced by factors...
• What is the optimal format of self-management education (including the information content, individualisation of the plan, written or electronic delivery, professional or lay educators) in order to ensure effective communication with patients (often from deprived communities), facilitation of ...
Sample size In a previous study of prostacyclin effect in 20 patients, an increase from 177 ± 60 mmHg to 213 ± 67 mmHg was observed for PaO2/FiO2,which was significant at the 0.01 level in an intraindividual comparison [9]. Recalculation showed that the standard deviation was con...
