Comparative analysis of the nitric oxide production by Leishmania sp.
Article in Medical microbiology and immunology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
The present report explores a comparative analysis of nitric oxide (NO(*)) production by three different species of Leishmania (L. amazonensis, L. braziliensis and L. chagasi). Among these species, L. braziliensis produced the highest amount of NO(*), measured in the supernatants of promastigotes cultures as nitrite, a stable by-product derived from NO(*). We have previously described the expression of a constitutive nitric oxide synthase (cNOS) in L. amazonensis promastigotes and axenic amastigotes. Comparing those results with the present work, using immunofluorescence assay, it was shown that both L. braziliensis and L. chagasi also express a cNOS. Immunostaining experiments showed that promastigotes from early passages of these species in culture had a strong immunoreactivity against anti-cNOS and anti-endothelial cell NOS, in comparison with the same parasite cultured for long time, suggesting a correlation between the NO(*) production and the presence of metacyclic forms prominent in those newly isolated parasites. These data corroborate findings of a higher NO(*) production by those parasites, following the growth curve. The relationship between the two NO(*)-generating systems in the parasite and in their host cell warrants further investigation. The presence of cNOS raises the possibility of a similar type of cross-talk or down-regulation between the NO(*) signaling systems in host cells and the lower eukaryotic-like Leishmania sp.
