Size does matter: ureteral stents with a smaller diameter show advantages regarding urinary symptoms, pain levels and general health.
Trial report in World journal of urology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers, 1 of them a synthesis that pooled 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.
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 effect of different diameters of ureteral stents (F4.7, F6, and F7) on quality of life regarding the subdomains of the Ureteral Stent Symptom Questionnaire. MATERIALS AND
methodsAll patients undergoing URS between April 2016 and July 2017 were prospectively randomised for ureteral stents F4.7, F6 and F7, respectively. All patients with other pathologies than a ureter stone, ureteral stents on both sides or other therapy than a secondary URS were excluded. Readmitted patients were interviewed using the USSQ. Furthermore, success rates of the second URS were also noted.
resultsBetween April 2016 to July 2017, 181 patients were included, 48 with a ureteral stent F4.6, 66 with F6 and 67 with F7. No significant differences in age, gender or position of the stones before URS were found (all p > 0.5). Comparing scores of USSQ between F4.7 and F6 or F6 and F7, scores were in favour of the smaller stent, but significance was only reached in "Work performance score" (F6-F7, p = 0.04) and "Urinary index score" (F4.7-F6, p = 0.004). When comparing F4.7 with F7, significant differences in all subgroups in favour of F4.7 were documented (all p < 0.03). Surgical success of the second URS was comparable in all groups (all above 82%, p > 0.15).
conclusionDiscomfort and pain increase with the diameter of the indwelling ureter stent, while the success of the following URS is not compromised by a ureter stent with a smaller diameter. Therefore, ureteral stents with a small diameter should be preferred.
