Serovar-specific immune responses to peptides of variable regions of Chlamydia trachomatis major outer membrane protein in serovar D-infected women.
Article in Clinical and experimental medicine, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The role of major outer membrane protein (MOMP) variable regions in the interaction of chlamydiae and host cells has been evaluated and their role in neutralization of antibodies has been clearly demonstrated. There are also studies that delineate the contribution of these regions to the cell-mediated immune response of the host and suggest that serovar E elicits serovar-specific immune responses in infected humans. However, further studies with other serovars are required to confirm these findings and to elucidate the role and importance of serovar-specific responses of variable regions of MOMP in other serovars. We, therefore, performed a detailed analysis of the humoral and cellular immune responses against the serovar D-specific variable segments (VS) of MOMP in women infected with Chlamydia trachomatis. We found that VS4 elicits significantly higher responses (both humoral and cellular) than other VS peptides (VS1, VS2 and VS3). VS4 elicited significantly higher (P < 0.0001) proliferative responses, interferon-gamma levels (P < 0.0001) as well as higher prevalence (P < 0.0001) of IgG antibodies against VS4 in serovar D-infected patients as compared to patients infected with other serovars, suggesting its role in serovar-specific immune responses.
