Resting plasma and salivary IL-6 concentrations are not correlated in distance runners.
Article in European journal of applied physiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Measurement of IL-6 has been widely undertaken to examine inflammatory and immune responses to exercise. Use of salivary IL-6 offers an alternative to the invasive collection procedures required for IL-6 measurement in plasma samples. Rarely, however, has the degree of association between plasma and salivary IL-6 been reported. The aim of the current study was to investigate the relationship between resting salivary and plasma IL-6 concentrations in 45 trained distance runners (36 males, 9 females; age: 35.1 +/- 8.0 y, mean +/- SD). Plasma and saliva samples were collected from athletes under resting conditions. Plasma IL-6 concentrations were determined using a Bioplex suspension array system and commercially available reagents. Salivary IL-6 concentrations were determined using a commercially available high-sensitivity ELISA kit. At rest, the mean (+/- SD) plasma IL-6 concentration was 3.43 +/- 3.75 pg mL(-1) compared to a mean salivary IL-6 concentration of 1.80 +/- 4.25 pg mL(-1). IL-6 concentrations in plasma and saliva samples were not correlated (r = -0.031, p = 0.85). At rest, salivary IL-6 concentrations do not reflect plasma IL-6 concentrations. The potential for salivary IL-6 to act as a surrogate marker for plasma IL-6 responses when examining inflammatory and immune responses to exercise, therefore, appears unlikely.
