Diagnostic Assessment of Lower Urinary Tract Symptoms in Men Considering Prostate Surgery: A Noninferiority Randomised Controlled Trial of Urodynamics in 26 Hospitals.
Trial report in European urology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers.
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
backgroundProstate surgery can improve lower urinary tract symptoms (LUTS) by relieving bladder outlet obstruction (BOO). However, surgery is less effective without BOO, or if detrusor underactivity is present. Urodynamics (UDS) can identify BOO and measure detrusor activity, but evidence in clinical practice is lacking.
objectiveUrodynamics for Prostate Surgery Trial: Randomised Evaluation of Assessment Methods (UPSTREAM) aimed to evaluate whether a care pathway including UDS would reduce surgery without increasing urinary symptoms. DESIGN, SETTING, AND
participantsUPSTREAM is a pragmatic, noninferiority, randomised controlled trial in men with bothersome LUTS, in whom surgery was an option, in 26 hospitals in England (ISRCTN56164274).
interventionParticipants were randomised (1:1) to routine care (RC) diagnostic tests, or RC plus UDS. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the International Prostate Symptom Score (IPSS; patient-reported outcome scale from 0 to 35 points) 18 mo after randomisation, with a noninferiority margin of 1 point. Urological surgery rates were a key secondary outcome. The primary outcome was compared between the arms using linear regression, analysed on an intention-to-treat basis. RESULTS AND LIMITATIONS: Between October 2014 and December 2016, 820 men (median age 68 yr) were randomised (393 and 427 in the RC and UDS arms, respectively). The UDS arm showed noninferiority of the mean IPSSs (UDS 12.6; RC 13.1; adjusted difference at 18 mo -0.33 [95% confidence interval {CI} -1.47, +0.80]). In the UDS arm, 153/408 (38%) received surgery compared with 138/384 (36%) in the RC arm (adjusted odds ratio 1.05; 95% CI 0.77, 1.43). A total of 428 adverse events (UDS 234; RC 194) were recorded, with related events similar in both arms and 11 unrelated deaths.
conclusionsIn this population, the UDS randomised group was noninferior to RC for the IPSS but did not reduce surgical rates. This study shows that routine use of UDS in the evaluation of uncomplicated LUTS has a limited role and should be used selectively. PATIENT SUMMARY: For men with uncomplicated lower urinary tract symptoms, symptom improvements after treatment and the number of operations performed are similar, irrespective of whether or not urodynamic tests are conducted in addition to routine tests. Accordingly, routine use of urodynamics has a limited role in this population group.
