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

backgroundMost studies have analyzed the urodynamic characteristics of patients with Parkinson's disease (PD) and multiple system atrophy (MSA) using conventional urodynamic studies.

objectivesThis study investigated the urodynamic characteristics of both diseases using video urodynamic study (VUDS).

methodsVUDS results from November 2004 to September 2020 were retrospectively analyzed at Seoul National University Hospital. The VUDS findings in patients with PD and those with MSA were compared. Movement disorder specialists diagnosed patients with PD and MSA.

resultsA total of 709 patients, comprising 364 PD (260 men, 104 women) and 345 MSA (215 men, 130 women) cases, were identified. Patients with MSA had a significantly younger age at onset, lower maximum flow rate (Qmax), larger postvoid residual volume, higher rate of poor bladder compliance, higher prevalence of urinary incontinence, and lower detrusor pressure at Qmax than those with PD. Among the fluoroscopic findings of VUDS, patients with MSA had a higher rate of incompetent bladder neck (18.8% vs. 4.7%, P < 0.001), bladder trabeculation (33.0% vs. 17.0%, P < 0.001), and vesicoureteral reflux (2.9% vs. 0.5%, P = 0.019) than those with PD. In VUDS performed in patients without urinary incontinence in conventional urodynamic study, an incompetent bladder neck was found in 14.6% of patients with MSA and 3.3% of patients with PD (P < 0.001).

conclusionsOur results demonstrate that VUDS can provide additional information on bladder urethral dysfunction, particularly regarding the risk of upper urinary tract damage and bladder neck status in patients with PD and MSA.
