Intravenous injection of Candida-derived mannan results in elevated tumor necrosis factor alpha levels in serum.
Article in Infection and immunity, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Intravenous injection of Candida albicans into mice produced elevated serum tumor necrosis factor alpha (TNF-alpha) levels. We hypothesized that immunostimulants released in vivo from C. albicans during fungal sepsis might contribute to the elevated levels of TNF-alpha in serum. We tested this hypothesis in mice with C. albicans mannan (CAM). Increased serum TNF-alpha levels were observed following intravenous and intraperitoneal injections of CAM. Injection of CAM into mice resulted in increased serum TNF-alpha concentrations that reached 1,200 pg/ml of blood, compared with 2,400 microg/ml of blood following injection of 10 microg of endotoxin. The response to CAM was concentration dependent, requiring a minimum dose of 20 microg of CAM per g of body weight. Sera from mice were tested 30, 60, 90, and 120 min after intravenous injections with CAM. TNF-alpha concentrations were minimal 30 and 120 min after intravenous injection and maximal 60 and 90 min after CAM injection. The relative distribution of CAM in vivo in decreasing order was determined to be as follows: blood > liver > lung > spleen, 90 min following injection of a single 5-mg dose of CAM. CAM was confirmed as the stimulating substance by utilizing anti-CAM antibodies in vivo to block the response. Rabbit anti-mannan antibodies administered by intraperitoneal injection 24 h before CAM injection significantly suppressed (P < 0.05) the accumulation of TNF-alpha in the sera. Dexamethasone administered to mice before intravenous injection of mannan significantly reduced (40 to 90% reduction; P < 0.05) the concentrations of TNF-alpha in the sera of treated mice. Thus, when in vivo CAM clearance mechanisms are exceeded, sufficient CAM may become available to stimulate TNF-alpha production, making CAM an important part of pathogenesis in Candida sepsis.
