Because of the unreasonable and unnecessary weight restriction assumption, a barely noticeable deficiency in pseudo-inefficiency occurs at times when applying a CCR model. The CCR was the first model designed for Data Envelopment Analysis (DEA); it remains its most popular model. To detect this type of unobvious deficiency, this study compared the following: the efficiency score and optimal wei...
OBJECTIVE To determine whether the use of cardiocerebral resuscitation (CCR) or AHA/ERC 2005 Resuscitation Guidelines improved patient outcomes from out-of-hospital cardiac arrest (OHCA) compared to older guidelines. DESIGN Systematic review and meta-analysis. DATA SOURCES MEDLINE, EMBASE, Web of Science and the Cochrane Library databases. We also hand-searched study references and consulte...
BACKGROUND The Canadian C-Spine (cervical-spine) Rule (CCR) and the National Emergency X-Radiography Utilization Study (NEXUS) Low-Risk Criteria (NLC) are decision rules to guide the use of cervical-spine radiography in patients with trauma. It is unclear how the two decision rules compare in terms of clinical performance. METHODS We conducted a prospective cohort study in nine Canadian emerg...
conclusions as about 70% of methicillin-resistant isolates belonged to sccmec iii, the present study can conclude that, over an 8-year period, only one dominant and stable clone of mrsa strain was found in tabriz hospitals. this finding could be a result of incorrect medical orientations, inadequate infection controlling policies, and insufficient preventive approaches. objectives the current s...
تکنیک های سری زمانی، در حال حاضر، در سطح گسترده ای از مطالعات علم اقتصاد و رشته های مرتبط مورد استفاده قرار می گیرد. برای به کارگیری این تکنیک ها، باید فروضی تأمین گردند که عدم تأمین انهاپیامدهایی را برای برآوردهای پارامترهای مدل در بر خواهد داشت. یکی از این تکنیک ها که به دلایلی در سطح وسیع در مقالات و پایان نامه ها مورد استفاده قرار می گیرد، مدل ardl (خودرگرسیونی با توزیع با وقفه) می باشد. به...
Glomerular filtration rate (GFR) is commonly assessed by measurement of endogenous creatinine clearance (Ccr). Several formulae have been described to calculate Ccr from plasma creatinine. I have evaluated the effectiveness of four formulae in 35 healthy subjects (21M and 14F, 18-34 years) and in 41 patients (24M, 17F, 20-69 years) attending a renal clinic with diminished renal function (serum ...
This multicenter, randomized, open-label, phase 3 trial evaluated azacitidine efficacy and safety vs conventional care regimens (CCRs) in 488 patients age ≥65 years with newly diagnosed acute myeloid leukemia (AML) with >30% bone marrow blasts. Before randomization, a CCR (standard induction chemotherapy, low-dose ara-c, or supportive care only) was preselected for each patient. Patients then w...
AIM To evaluate the relationship between creatinine clearance rate (CCR) and the level of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in heart failure (HF) patients and their correlations with HF severity. METHODS AND RESULTS Two hundred and one Chinese patients were grouped according to the New York Heart Association (NYHA) classification as NYHA 1-2 and 3-4 groups and 135 cases ou...
ccr encoding crotonyl coenzyme A (CoA) reductase (CCR), which catalyzes the conversion of crotonyl-CoA to butyryl-CoA in the presence of NADPH, was previously cloned from Streptomyces collinus. We now report that a complete open reading frame, designated meaA, is located downstream from ccr. The predicted gene product showed 35% identity with methylmalonyl-CoA mutases from various sources. In a...
This paper compares the finite sample performance of the canonical correlation regression estimator (CCR) and Stock and Watson's (A simple estimator of cointegration vectors in higher order integrated systems, Econometrica, 1993, 61(4), 783-820) dynamic ordinary least squares estimator (DOLS) using the models proposed by Inder (Journal of Econometrics, 1993, 57, 53-68). The CCR estimator shows ...
