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

purposeChronic prostatitis/chronic pelvic pain syndrome causes symptoms that include the frequent and urgent need to urinate, pain or burning during urination and pain radiating to the back, abdomen and/or colorectum. These bladder symptoms suggest that chronic prostatitis/chronic pelvic pain syndrome is associated with sensitization of adjacent organs, termed cross-organ sensitization. The objective of this study was to determine the extent of 1) changes in immunomodulatory mediators in the prostate and bladder after inflammation of the prostate and 2) bladder function and bladder afferent sensitization. MATERIALS AND

methodsProstate and bladder histology, immunohistochemistry and expression of immunomodulatory targets were examined weekly after zymosan or vehicle was injected in the dorsal lobe of the mouse prostate. Cystometry, bladder and bladder afferent sensitivity were also assessed weekly.

resultsProstate inflammation induced significant up-regulation in proinflammatory and anti-inflammatory cytokines TNF-α (tumor necrosis factor-α) and IL-10 (interleukin-10), growth factor NGF (nerve growth factor), and T-lymphocyte markers FoxP3, CD4 and CD8 in the prostate and the bladder. Notably, prostatitis significantly increased urinary voiding frequency, induced hypersensitivity to bladder distension and sensitized bladder afferents. We also examined sensory (afferent) co-innervation by injecting retrograde tracers DiI and Fast Blue in the bladder wall and the prostate, respectively. This showed that a significant proportion (approximately 17%) of dorsal root ganglion afferent somata contained tracers from the bladder and the prostate.

conclusionsThese observations support an afferent contribution to chronic prostatitis/chronic pelvic pain syndrome and cross-organ sensitization from prostate to bladder.
