1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundUrodynamic studies (UDS) are integral to the evaluation and management of lower urinary tract dysfunction. However, artifacts are frequently encountered, affecting both clinical interpretation and research reliability.

objectiveThis expert narrative review examines the prevalence, classification, and clinical relevance of artifacts encountered during UDS, based on findings from the existing literature.

methodsA focused literature review was conducted, analyzing studies that reported data on the sources and impact of UDS artifacts, particularly from the patient perspective. Emphasis was placed on identifying both technical and patient-related contributors to artifact generation.

resultsArtifacts are common in UDS despite adherence to Good Urodynamic Practices recommended by the International Continence Society. Technical artifacts may stem from equipment-related issues such as calibration errors, catheter displacement, and device variability. Patient-related artifacts can arise from physical movement or test-induced detrusor overactivity. These artifacts may lead to misinterpretation, misdiagnosis, and inappropriate interventions in clinical practice. Furthermore, they may affect the validity of research findings related to diagnostic tools for lower urinary tract symptoms.

conclusionIdentifying and addressing UDS artifacts during the procedure or in post-test interpretation is critical for accurate clinical decision-making and reliable research outcomes. Efforts to minimize artifacts should be prioritized to improve the quality and utility of UDS.
