Differential associations between brain 5-HT(1A) receptor binding and response to pain versus touch.
Article in Journal of neural transmission (Vienna, Austria : 1996), 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We studied whether brain serotonin 5-HT(1A) receptor availability is associated with response to noxious heat versus tactile stimuli, and short-term memory for heat pain. Psychophysical performance was assessed in 16 healthy subjects who had participated in a positron emission tomography study using [carbonyl-11C]WAY-100635 ligand for the assessment of 5-HT(1A) receptor binding potential (BP (ND)). Signal detection theory was applied to allow separate analysis of the subject's sensory-discriminative capacity (sensory factor) and the attitude toward reporting a sensation (response criterion; non-sensory factor). Subject's response criterion for heat pain was inversely correlated with 5-HT(1A) BP (ND) in the dorsal raphe, middle temporal gyrus, orbitofrontal cortex and posterior cingulum, whereas the subject's discriminative capacity for touch was inversely correlated with 5-HT(1A) BP (ND) in the cingulum, inferior temporal gyrus, and medial prefrontal cortex. Certainty ratings of the responses, but not hit rates, in the pain memory task were correlated with 5-HT(1A) BP (ND) in the dorsal raphe.
