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

purposeThis study presents characteristic cystoscopic findings for Hunner's and non-Hunner's interstitial cystitis/bladder pain syndrome (HIC and NHIC) and their association with bladder wall morphology assessed by computed tomography (CT) and urodynamic parameters.

methodsCystoscopic images and bladder CT from 212 patients diagnosed with HIC (n = 52) and NHIC (n = 160) were retrospectively reviewed. The correlations between cystoscopic findings and abdominal CT findings, urodynamic parameters and urinary biomarkers at baseline were examined.

resultsSignificantly lower bladder capacity was noted in patients with HIC than NHIC. Hunner's lesions could usually be identified through office-based cystoscopy without anesthesia. Different grades of glomerulation developed after cystoscopic hydrodistention in NHIC. Grade 0 or 1 glomerulation was observed in 77 (48.1%) NHIC patients, and grade 2 or 3 glomerulation in 83 (51.9%). The bladder wall thickness (BWT) in all patients with HIC showed focal or diffuse thickening on bladder CT. The rate of focal or diffuse bladder wall thickness was higher in NHIC patients with maximal bladder capacity (MBC) < 760 ml (54.5%) than ≥ 760 ml (28.7%) (p = 0.001). However, bladder wall thickness was not associated with glomerulation grade. The sites of focal BWT for Hunner's lesions were strongly correlated with the cystoscopic findings. Urinary inflammatory and oxidative stress biomarker levels were significantly higher in patients with HIC than NHIC, and inflammatory biomarkers were significantly higher in patients with diffuse BWT than those with focal BWT and smooth BWT. This study also showed characteristic cystoscopic findings of HIC and NHIC.

conclusionHunner's lesions have distinct cystoscopic features and focal or diffuse BWT in bladder CT. Careful examine cystoscopic findings and bladder CT can accurately diagnose HIC and NHIC and facilitate earlier, more effective treatment.
