Early in life bladder inflammation alters opioid peptide content in the spinal cord and bladder of adult female rats.
Article in The Journal of urology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
purposePrevious research suggests that a failure of opioid inhibition may contribute to chronic bladder pain. We determined how acute adult and/or prior early in life exposure to bladder inflammation alters the adult content of endogenous opioid peptides in the bladder, spinal cord and blood. MATERIALS AND
methodsInflammation was induced by intravesical administration of zymosan. Female Sprague-Dawley® rats were exposed to anesthesia only or zymosan early in life (postnatal days 14 to 16) and anesthesia only or zymosan as adults (ages 12 to 17 weeks). Thoracolumbar and lumbosacral segments of the spinal cord, and blood and bladders were collected 24 hours after adult treatment. Opioid peptide content was measured using enzyme-linked immunosorbent assay.
resultsEarly in life bladder inflammation alone produced a chronic increase in dynorphin A (1-17) in the lumbosacral spinal cord. When early in life inflammation was followed by adult re-inflammation, spinal cord dynorphin remained unchanged but bladder dynorphin was decreased. In addition, early in life inflammation combined with adult bladder inflammation decreased endomorphin-2 content in the thoracolumbar spinal cord. Neither early in life nor adult bladder inflammation affected thoracolumbar dynorphin, serum dynorphin, lumbosacral endomorphin-2 or plasma β-endorphin.
conclusionsSeveral opioid peptides were measured using enzyme-linked immunosorbent assay following early in life and adult bladder inflammation. The changes observed are consistent with the view that early in life bladder inflammation alone can chronically alter spinal cord peptide content. When coupled with adult re-inflammation, these changes could set the neurochemical stage to support bladder hypersensitivity.
