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

objectiveTo compare the stent-related symptoms (SRS) of three commonly used, readily accessible ureteric JJ stents after uncomplicated flexible ureteroscopic lithotripsy (FURL), in a prospective randomised controlled single-blind parallel-group study, in order to see whether structural difference might influence SRS. PATIENTS AND

methodsPatients undergoing FURL were randomised into three groups: the Cook Group received conventional 6 F Cook Universa Soft JJ stents as control, the Kang Yi Bo (KYB) Group received 6 F KYB anti-reflux JJ stents, and the Urovision Group received 7 F Urovision Visiostar ESWL JJ stents. The ureteric stent symptom questionnaire (USSQ) was administered at 1 week, 4 weeks (before stent removal), and 5 weeks (one week after stent removal as baseline evaluation) after stent insertion. Both raw and baseline-adjusted USSQ domain subscores at 1 week and 4 weeks were compared.

resultsA total of 146 patients were included in the analysis. The KYB Group showed significantly lower P6&7 subscore yet higher urinary symptoms score 1 week and 4 weeks after stents insertion than both Cook and Urovision, whilst the Urovision Group achieved similar scores in most domains with Cook.

conclusionsAlthough the KYB anti-reflux JJ stent might prevent vesicoureteral reflux, it induces significantly stronger urinary symptoms, both at 1 week or 4 weeks after stent insertion, with or without baseline correction. Despite the unique triangular prismatic shape, the Urovision Visiostar stent does not cause heavier urinary symptoms or pain compared to the conventional cylinder shape counterparts.
