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
In the present work, we analyzed the humoral response of Leishmania major experimentally infected BALB/c and C57BL/6 mice against three Leishmania antigens: total soluble antigen (soluble leishmania antigen(SLA)), a chimerical recombinant protein formed by the genetic fusion of four cytoplasmic proteins (PQ), and a kinetoplastic membrane protein (Kmp-11). We determined the correlation between the immune response against these proteins and the histopathological changes induced in the susceptible and resistant mice after infection. The data showed the existence of wide differences in the recognition of SLA, PQ, and Kmp-11 by the sera from both strains. The anti-SLA titer of BALB/c was 100 times higher than that of C57BL/6 mice. Antibodies against the recombinant Kmp-11 were detected only in infected BALB/c during the first stage of the infection. In contrast, the PQ protein was recognized by the sera from infected BALB/c mice but exclusively when they were in a late-lesion period. The data suggest that the response against the membrane Kmp-11 protein is transient and correlates with early developmental stages of the infection, whereas the response against cytoplasmic proteins as those present in PQ is sustained and could be considered as a marker of an advanced stage of the infection and disease.
