How the survey began The SOR is composed of two resident representatives from each Canadian family medicine (FM) residency program. Since 1995, the SOR’s Survey Committee has surveyed FM residents across the country about their residencies. The CFPC developed a comprehensive database on family physicians through the Janus Project: Family Physicians Meeting the Needs of Tomorrow’s Society in 199...

For children with primary nocturnal enuresis, treatment with enuresis alarms reduced the number of wet nights by almost 4 per week, with almost half of patients remaining dry for 3 months after treatment (strength of recommendation [SOR]: A, based on a systematic review of homogeneous randomized control trials [RCTs]). Desmopressin (DDAVP) and tricyclic drugs reduce the number of wet nights by ...

The eigenvalue problem Ax = \Bx, where A and B are large and sparse symmetric matrices, is considered. An iterative algorithm for computing the smallest eigenvalue and its corresponding eigenvector, based on the successive overrelaxation splitting of the matrices, is developed, and its global convergence is proved. An expression for the optimal overrelaxation factor is found in the case where A...

This paper considers the synchronized output regulation (SOR) problem of nonlinear multi-agent systems with switching graph. The SOR means that all agents regulate their outputs to synchronize on the output of a predefined common exosystem. Each agent constructs its local exosystem with the same dynamics as that of the common exosystem and exchanges the state information of the local exosystem....

Vietnamese word segmentation (VWS) is a challenging basic issue for natural language processing. This paper addresses the problem of how does dictionary size influence VWS performance, proposes two novel measures: square overlap ratio (SOR) and relaxed square overlap ratio (RSOR), and validates their effectiveness. The SOR measure is the product of dictionary overlap ratio and corpus overlap ra...

In this paper we give the optimum parameters for the Accelerated Overrelaxation (AOR) method in the special case where the matrix coefficient of the linear system, which is solved, is consistently ordered with nonvanishing diagonal elements. Under certain assumptions, concerning the eigenvalues of the corresponding Jacobi matrix, it is shown that the optimum AOR method gives better convergence ...

■ EVIDENCE-BASED ANSWER For grade 3 and 4 ankle sprains, ice works better than heat to speed recovery (return to play) (strength of recommendation [SOR]: B, based on a single retrospective cohort study). No studies support faster return to play with the application of heat at any time after injury (SOR: B, based on head-to-head randomized trials). Ice therapy also reduces edema, but the clinica...

A diet high in fiber (particularly fruit and vegetable fiber) and low in fat and red meat may help to decrease the risk of symptomatic diverticular disease (strength of recommendation [SOR]: C, case-control studies and a large prospective cohort study). For people with diverticular disease, a diet high in fiber might decrease the risk of complications (SOR: C, case series). No studies have eval...

Evidence-Based Answer Surgery should not be offered to patients with asymptomatic cholelithiasis. (Strength of Recommendation [SOR]: C, based on decision analysis, observational studies, and expert opinion.) Cholecystectomy may be beneficial for patients who are at high risk of biliary cancer, infection, or other complications, including younger patients and those with choledocholithiasis, sick...

A It’s impossible to say for certain in the absence of randomized controlled trials. However, in patients whose impingement symptoms don’t improve after 3 to 6 months, arthroscopic subacromial decompression (ASD) is associated with modest (about 10%) longterm improvement in pain and function compared with open acromioplasty or baseline (strength of recommendation [SOR]: B, cohort studies). Pati...
