Immunohistochemical localization of carbonic anhydrase IV in the human parotid gland.

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
Carbonic anhydrases (CAs) catalyze the hydration and dehydration of carbon dioxide. They are important for regulating ions, fluid and acid-base balance in many tissues. The location of CAs by cell type is important for understanding their roles in these functions. CAs II and VI have been demonstrated using immunohistochemistry (IHC) in the serous acinar cells of human salivary glands and ducts of rat salivary glands. CA IV has been localized by IHC to the ducts of rat salivary glands. CA IV also is present in human parotid glands as shown by real time-polymerase chain reaction (RT-PCR), but this method does not show the distribution of the CA isozymes by cell type. We investigated the cell-specific distribution of CA IV in the human parotid gland. Sections from five formalin fixed, paraffin embedded specimens of human parotid gland were subjected to IHC for CA IV using a commercial antibody. Moderate to strong reactions were found in the cell membranes and cytoplasm of the intercalated, striated and excretory ducts and capillaries, and reactions in the acini were limited to faint areas in some cells. These results indicate that CA IV participates in the regulation of bicarbonate/carbon dioxide fluxes in the ductal system of the human parotid gland.
