Effect of Efflux Transporter Inhibition on the Distribution of Fluconazole in the Rat Brain.
Article in Neurochemical research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Multidrug resistance-associated proteins (MRPs) and organic anion transporters (OATs) are expressed on the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCSFB), preventing the entry of or the pumping out of numerous molecules. Fluconazole is widely used to treat fungal meningoencephalitis. The effect of these transporters on the distribution of fluconazole in the brain is unclear. We used microdialysis to compare the distribution of fluconazole in the rat brain with and without co-administration of probenecid, a MRP and OAT inhibitor. Additionally, we also observed the difference in fluconazole distribution between the two barriers. The results showed that probenecid increased the penetration of fluconazole into the BBB but did not alter the penetration of fluconazole into the BCSFB of rats. The penetration of the BBB and BCSFB by fluconazole did not statistically differ according to physiological condition. These results demonstrate that transporters that can be inhibited by probenecid may be involved in fluconazole resistance at the BBB and provide a laboratory basis for predicting brain extracellular fluid (ECF) concentration using the cerebrospinal fluid (CSF) concentration of fluconazole.
