A polymorphism in the CCL2 chemokine gene is associated with asthma risk: a case-control and a family study in Tunisia.
Article in Genes and immunity, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
Asthma is a complex genetic disorder characterized by chronic airway inflammation. We hypothesized that genetic polymorphisms in chemokines and their receptors alter leukocyte mobilization and may thus influence the risk and severity of childhood asthma. Distributions of the chemokine CCL2-2578G, CCL2-927C, CCR2-V64I, CX3CR1-V249I and CX3CR1-T280M receptor polymorphisms were examined in a case-control study of 121 children with asthma and 226 age-matched healthy controls and then replicated in a family study of 99 simplex families (297 individuals). The case-control study revealed that the CCL2-2578G allele was less frequent in children with than in those without asthma (P=0.0012). No association with asthma was found for the CCL2-927, CCR2 or CX3CR1 polymorphisms. The finding in the family study that the CCL2-2578G allele was transmitted less often by heterozygous parents to their children with asthma (P=0.0016) confirms the association of CCL2-2578G with asthma risk. Biochemical studies indicated that plasma CCL2 concentrations were higher in both patients (P=0.0214) and controls (P=0.001) carrying the G allele than in subjects with other polymorphisms. Both case-control and family-based studies suggest a protective effect of allele CCL2-2578G in Tunisian asthmatic children.
