UDP-galactopyranose mutases from Leishmania species that cause visceral and cutaneous leishmaniasis.
Article in Archives of biochemistry and biophysics, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Leishmaniasis is a vector-borne, neglected tropical disease caused by parasites from the genus Leishmania. Galactofuranose (Galf) is found on the cell surface of Leishmania parasites and is important for virulence. The flavoenzyme that catalyzes the isomerization of UDP-galactopyranose to UDP-Galf, UDP-galactopyranose mutase (UGM), is a validated drug target in protozoan parasites. UGMs from L. mexicana and L. infantum were recombinantly expressed, purified, and characterized. The isolated enzymes contained tightly bound flavin cofactor and were active only in the reduced form. NADPH is the preferred redox partner for both enzymes. A kcat value of 6 ± 0.4s(-1) and a Km value of 252 ± 42 μM were determined for L. infantum UGM. For L. mexicana UGM, these values were ∼4-times lower. Binding of UDP-Galp is enhanced 10-20 fold in the reduced form of the enzymes. Changes in the spectra of the reduced flavin upon interaction with the substrate are consistent with formation of a flavin-iminium ion intermediate.
