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

backgroundEosinophilic cystitis (EC) is rare in children and remains poorly understood. Our aim was to analyse the clinical and imaging features of eosinophilic cystitis in children.

methodsA retrospective review of histologically confirmed eosinophilic cystitis between January 2008 and December 2022 was performed, including patient age, sex, symptoms, laboratory examination, radiology, treatment and outcome.

resultsTwelve children (two girls, 10 boys; age range: 3-12 years, mean age: 7.2 years) were included in the study. Urinary irritation symptoms (10/12), haematuria (5/12) and hypogastralgia (3/12) were the most common symptoms. Five patients had a history of allergies, six patients had elevated serum IgE, nine patients had elevated peripheral eosinophils and six patients had positive microscopic haematuria. Radiology revealed diffuse homogeneous or inhomogeneous thickening in seven patients, localised thickening in three patients, and solitary tumour-like lesions in the other two patients. Preservation of the mucosal line and bladder wall layering were observed in eleven patients, and perivesical exudation and small vessel dilatation were observed in ten patients. All four patients with delayed scans showed obvious delayed enhancement. One patient showed low signal intensity on T2-W imaging. All patients received antihistamine, antibiotic and/or corticosteroid therapy and two tumour-like patients underwent transurethral resection. Nine patients achieved complete response and three patients achieved partial response.

conclusionThe clinical and imaging manifestations of EC in children have relative characteristics; when urologist and radiologist confronted with similar cases, EC should be considered. The final diagnosis depends on pathological biopsy.
