The LURN Urinary Urgency and Lifestyle Wearable Tracker (ULTra) study: Design and feasibility.

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.
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
Introduction: The ULTra study was designed to better understand the relationship of lifestyle factors with urinary urgency, specifically by assessing physical activity and sleep quality using a wearable tracker. Our objectives here are to describe study design and enrollment, adherence, and data evaluability results. Methods: The Urinary Urgency and Lifestyle Wearable Tracker (ULTra) study of the Symptoms of Lower Urinary Tract Dysfunction Research Network (LURN) is a 3-month, prospective study performed within the larger 1-year Urinary Urgency Phenotyping (UUP) study. The UUP and ULTra studies enrolled adults with bothersome urinary urgency without (URG) or with urgency urinary incontinence (UUI) and a sex- and age-matched control group (no urinary symptoms). Data collection using the wearable tracker, including steps, heart rate, logged physical activities, and sleep episode information, occurred over two weeks at baseline and again 3-months after enrollment. Adherence and data validity criteria were developed for physical activity and sleep data obtained via the wearable tracker. Results: We enrolled 270 participants (64 URG, 143 UUI, 63 controls), and 205 (76%) had evaluable data (at least 5 valid days) for either physical activity or sleep. In cases, data evaluability differed by sex, but not by age or case-control status. Female participants (versus male) and those with higher comorbidity and incontinence scores were less likely to contribute evaluable data. Conclusion: This manuscript describes the design of the LURN ULTra study and discusses feasibility and challenges encountered in conducting a multicenter study employing wearable technology in an adult population seeking care for urinary symptoms.
