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

objectivesThe urinary proteome is a potential easily accessible source of biomarkers for inflammatory bladder diseases, including interstitial cystitis. In the present study, we subjected rat urine to multiplex cytokine analysis in an attempt to identify an inflammatory signature of the temporal course of cyclophosphamide (CYP)-induced cystitis.

methodsRat urine was collected for 12 hours after CYP injection (150 mg/kg) for multiplex analysis of 14 cytokines by a multiple antigen bead assay (Luminex 100 IS). Urine from each void was collected, and the voiding frequency was determined. The bladder tissue was analyzed for cytokines levels and histologic evidence of inflammation.

resultsSignificant changes were noted in the urine levels of all cytokines with respect to baseline at 2, 4, 6, and 10 hours after CYP injection. Elevation was noted at all times for most cytokines, except for monocyte chemotactic protein-1, which had a 5-fold decrease at 2 hours. The urine and tissue levels of interleukin (IL)-1beta, IL-4, and growth-related oncogene/keratinocyte-derived chemokine correlated significantly, with a positive Spearman correlation also noted for granulocyte-macrophage colony-stimulating factor, monocyte chemotactic protein-1-1, IL-18, and interferon-gamma. The tissue levels for most cytokines, except for IL-2, and urinary frequency were significantly elevated in the CYP-treated rats compared with the control vehicle-treated rats. The hints of severe inflammation in the bladder indicated by the urinary cytokines were confirmed by bladder histologic examination and the tissue cytokine levels at necropsy.

conclusionsThe progression of CYP-induced cystitis was clearly reflected in the urine matrix by the temporal and quantitative changes in the cytokine levels. Additional delineation of urine and bladder tissue cytokine expression might yield biomarkers for cystitis.
