Comparison of transection techniques in pediatric major hepatectomy: a matched pair analysis

HPB, 2023
Evidence on safety and efficacy of different liver transection techniques in pediatric major hepatectomy is completely lacking, as no study has been conducted so far. The use of stapler hepatectomy has never before been reported in children.Three liver transection techniques were compared: (1) ultrasonic dissector (CUSA), (2) tissue sealing device ...

Bayesian Analysis of Matched Pairs in the Presence of Covariates

2003
Abstract In this paper, we address three main questions connected with the statistical analysis of matched pairs in the presence of covariates, from a Bayesian viewpoint. These sort of data appear when measurements are made on the same individuals before and after a treatment, at possibly different dose levels, is applied.

Is mesenteric panniculitis truely a paraneoplastic phenomenon? A matched pair analysis

European Journal of Radiology, 2013
Mesenteric panniculitis (MP) is an underdiagnosed inflammatory condition of mesenteric adipose tissue. Prior studies suggested an association of MP with malignancy. To reassess this hypothesis, we performed the first matched case-control study comparing prevalence of malignancy and other disease in patients with and without MP.With a keyword search we ...

Squamous cell carcinoma of the tongue in young patients: A matched-pair analysis

Head & Neck, 1998
Tongue cancer is seen with increasing frequency in young individuals. There is controversy concerning the clinical course and outcome for oral tongue cancer in young patients.A retrospective review of 36 patients under 40 years of age with squamous cell carcinoma of the tongue was performed. These patients were matched to an older population.

COMPARISON OF 2 GENERATIONS OF PIEZOELECTRIC LITHOTRIPTORS USING MATCHED PAIR ANALYSIS

Journal of Urology, 2004
The Piezolith 3000 (Richard Wolf, Knittlingen, Germany) is the newest piezoelectric lithotriptor. Using a matched pair analysis model we compared treatment outcomes of this machine with those of an older generation Piezolith 2300 lithotriptor (Richard Wolf).Patients with solitary, radio-opaque urinary calculi undergoing primary lithotripsy using the ...

A MATCHED-PAIRED COMPARATIVE ANALYSIS OF THE HEMODYNAMICS OF THE TRIFECTA AND PERIMOUNT AORTIC BIOPROSTHESES

Canadian Journal of Cardiology, 2015
Current cohort studies comparing the Trifecta valve to alternative pericardial bioprostheses are limited by selection bias. The study aim was to determine if hemodynamics are improved after the aortic valve implantation of a Trifecta valve as compared to a standard pericardial valve, when evaluated using strict paired matching for specific key relevant

Matched Pair Analysis of Shock Wave Lithotripsy Effectiveness for Comparison of Lithotriptors

Journal of Urology, 2003
In an effort to streamline a comparison of the effectiveness of a new lithotriptor with the standard HM3 lithotriptor (Dornier Medical Systems, Inc., Marietta, Georgia) we used a matched pair analysis design. A matched design often provides more efficient estimates (smaller variances) than an unmatched design given the same sample size.Patients with ...
