This is what would be expected, as the DOR is likely to be higher when those interpreting test results have access to appropriate clinical information similar to that, which would be available in practice. Ezamen method is known as the “bivariate model” [ ].


Comparative study between Uricult and urine culture for the diagnosis of urinary infections in infants. The model can be extended to include explanatory variables leading to separate effects on sensitivity and specificity. As in all previous groups, studies also provided very little information on whether appropriate clinical information was available when test results were interpreted, how uninterpretable results were handled, and whether there were any withdrawals from the study and if so whether all withdrawals were accounted for.

Study withdrawals and handling of uninterpretable results were also poorly reported. PW and MW participated in data extraction, the analysis of data, and drafted the article. Were selection criteria clearly described? Published online Jun 8. Abstract Background The use of systematic literature review to inform evidence based practice in diagnostics is rapidly expanding.

The value of urinalysis in differentiating acute pyelonephritis from lower urinary tract infection in febrile infants. This should have a positive impact on the quality of the diagnostic literature in the future. Was the execution of the reference standard described in sufficient detail to permit its replication?

Bavterioscopico African Medical Journal. The DOR was 3. Discussion The methodological quality of primary studies remains a significant issue for systematic reviews of diagnostic tests [ 8, ].

How does study quality affect the results of a diagnostic meta-analysis?

The use of systematic literature review to inform evidence based practice in diagnostics is rapidly expanding. Combining independent studies of a diagnostic test into a summary ROC curve: Sonographic detection of vesicoureteral reflux with fluid and air cystography. Acta Paediatrica Scandinavica Supplement.

Screening for vesicoureteral reflux in children using real-time sonography. The use of systematic literature review to inform evidence-based practice in diagnostics is rapidly exammen. The value of pyuria as a diagnostic criterion of urinary tract infections.


Whilst poor reporting remains a widespread problem, it is almost impossible to assess the impact of components of methodological quality on the results of diagnostic meta-analyses.

Are Newcastle urine collection pads suitable as a bacterioacopico of collecting specimens from infants? Bacterikscopico, we performed univariate analysis with all items included separately in the model.

The use of an appropriate reference standard was also an issue in some of these studies. Urine collection from disposable nappies. This meant that further analysis to investigate heterogeneity could only be undertaken using a subset of studies, and bacteripscopico the findings are open to various interpretations.

Early 99mTc dimercaptosuccinic acid DMSA scintigraphy in symptomatic first-time urinary tract infection. Comparison of sterile bag, clean catch and suprapubic aspiration in the diagnosis of urinary infection in early childhood. We therefore advocate that components of quality assessment should be reported fully, and their impact on outcome measures analysed individually rather than as summary scores. A method comparison study bactdrioscopico assess the reliability of urine collection pads as a means of obtaining urine specimens from non-toilet-trained children for microbiological examination.

This method takes the DOR as the dependent variable. Comparacion entre el estudio bacterioscopico cuantitativo y el urocultivo para el diagnostico de infeccion urinaria en pediatria.
