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

objectivesPrevious studies have shown conflicting results concerning the optimal duration of ureteral stenting after endourologic treatment of stone disease, its effect on patient comfort, and the necessity for emergent, unscheduled care. This study assessed the impact of stent duration, sex, and other patient-associated factors on reported pain scores using a large, international prospective registry.

methodsA prospective observational patient registry on ureteral stents from 10 institutions in 4 countries (United States, Canada, France, and Japan) from 2020-2023 was assessed. The primary outcome was Patient-Reported Outcomes Measurement Information System (PROMIS) pain intensity scores administered on the day of stent removal, before stent removal. Patients were grouped by indwelling time (short, medium, and long), and pain scores were compared. The impact of sex, height vs. stent length, and presence or absence of tether were assessed.

results359 patients were enrolled in the database, with outcomes analyzed for 268 patients with a unilateral stent placed after an endourologic procedure for stones. No significant difference was detected in pain scores between the indwelling time groups (p = 0.41). Height for a given stent length was not significantly associated with pain scores. There was no difference in pain scores with or without tether. Men reported lower pain scores than women (p = 0.018).

conclusionsThis study did not detect an overall difference in pain scores reported at stent removal within or between stent duration groups. Men reported less pain than women in this study, suggesting that patient factors may be more important than indwelling time when optimizing pain management.
