Low Risk for Urinary Tract Infection After Voiding Cystography in Children Without Dilated Vesikoureteral Reflux.

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
aimUrinary tract infection (UTI) is the most common and significant complication after voiding cystourethrography (VCUG) but the reported incidence in children varies highly. Therefore, the aim of this study was to evaluate the rate and possible risk factors for UTIs after VCUG.
methodA multicentre retrospective cohort study of children < 15 years of age undergoing VCUG between 2017 and 2022 was conducted. Lower UTI (cystitis) and febrile UTI (pyelonephritis) within 14 days of VCUG were registered, defined by clinical assessment and a positive urinary culture.
resultsOne thousand and one examinations were included (median age 1 year, 52% boys). Previous febrile UTI was present in 58%. Pathology was found in 47% of children, of which 83% had vesicoureteral reflux (VUR). Post VCUG UTI occurred in 34 (3.4%) children within 14 days, of which 60% were within 7 days and 88% were febrile. Only dilating VUR increased the risk for post VCUG UTI (adjusted odds ratio 5.4 [2.6-8.7] p < 0.001).
conclusionThere was a low rate of post VCUG UTIs. Since children with dilated VUR are at risk for chronic kidney injury, targeted interventions after VCUG could possibly lower additional UTIs in this group.
