Sublingual nucleotides and immune response to exercise.
Article in Journal of the International Society of Sports Nutrition, 2012. 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
Evidence exists regarding the potential role of exogenous nucleotides as regulators of the immune function in physically active humans, yet the potential use of nucleotides has been hindered by their low bioavailability after oral administration. We conducted a double-blind, placebo-controlled, randomized trial to assess the effect of sublingual nucleotides (50 mg/day) on salivary and serum immunity indicators as compared to placebo, both administered to healthy males aged 20 to 25 years for 14 days. Sublingual administration of nucleotides for 14 days increased serum immunoglobulin A, natural killer cells count and cytotoxic activity, and offset the post-exercise drop of salivary immunoglobulins and lactoferrin (P < 0.05), with no adverse effects reported. No significant differences in fasting salivary antimicrobal proteins (α-amylase, lysozyme and lactoferrin) were found before or after the treatment (P > 0.05). It seems that sublingual administration of nucleotides for two weeks considerably affected immune function in healthy males.
