Retrospective survey for sialidase activity in Mycoplasma pneumoniae isolates from cases of community-acquired pneumonia.
Article in BMC research notes, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSialidase is a well-known virulence factor of other respiratory pathogens, but was only recently documented to occur in some species of Mycoplasma. The sialidase activity expressed can vary quantitatively among strains within a species of mycoplasma, from undetectable to amounts that correlate positively with strain virulence. Very few isolates of Mycoplasma pneumoniae had ever been examined for sialidase activity, so it was unknown whether sialidase may contribute to diseases involving this species.
findingsNo sialidase activity was detected by spectrofluorometric assay of 15 laboratory strains and 91 clinical isolates of M. pneumoniae banked over many years from patients having radiologically-confirmed, uncomplicated community-acquired pneumonia.
conclusionsThe annotated genome of strain M129 (GenBank NC_000912, ATCC 29342), also isolated from a patient with pneumonia, accurately represents the absence of sialidase genes from strains of M. pneumoniae typically associated with uncomplicated community-acquired pneumonia. A possible involvement of sialidase in neurologic or other extra-respiratory manifestations of M. pneumoniae mycoplasmosis remains to be investigated.
