1 · What the graph read from it

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.

2 · The registry

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

Sera from patients with American visceral leishmaniasis (AVL) were studied before and after treatment based on their antibody isotypes and subtypes. The study was comprised of 33 Brazilian patients with well-defined diagnosis of AVL and 39 clinically healthy individuals. Antileishmanial antibody isotypes and subtypes were observed in almost all patients, except IgA that was detected in about 63% of them. The sensitivity and specificity of the immunofluorescence assay in the detection of antibody isotypes (IgG and IgM) and subtypes (IgG1, IgG2, IgG3, and IgG4) were high with no statistical difference, ranging from 0.937 to 1.000 and from 0.954 to 1.000, respectively. All IgG antibodies and its subtypes had their levels reduced after treatment. However, the IgG4 had an early decay and its conversion to negative was significantly high in children. Moreover, the profile of IgG4 before treatment corresponded to a unimodal curve that shifted to a patent bimodal curve after treatment, indicative of therapeutic success. Thus, the IgG4 shows to be a suitable immunological marker for the assessment of chemotherapy in AVL patients or communities. Our findings suggest that IgG4 correlates with IL-4 that also decreases after therapy.
