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

The relationship between Mycobacterium tuberculosis 50- to 55-kDa protein and Mycobacterium bovis BCG 45- to 47-kDa antigen was examined by using immunological and biochemical criteria. Reciprocal cross-reactivity with a rabbit polyclonal antiserum against the M. bovis BCG protein and with a monoclonal antibody raised against the M. tuberculosis antigen was observed. The epitope recognized by this antibody was apparently present only in proteins of M. tuberculosis and M. bovis BCG among the 11 mycobacterial species tested. The amino-terminal sequences and total amino acid contents of these proteins showed strong similarities. Both antigens are glycoproteins as assessed by binding of concanavalin A, labeling of carbohydrate moieties with biotin-hydrazide, and digestion of carbohydrates with jack bean alpha-D-mannosidase, which produced a reduction of the molecular weights of the proteins and totally eliminated concanavalin A binding. Both M. tuberculosis and M. bovis BCG proteins are secreted, since they were found mainly in the culture medium. Analysis of M. tuberculosis 50- to 55-kDa antigen by two-dimensional gel electrophoresis showed at least seven different components, as previously described for the M. bovis BCG antigen. Solid-phase immunoassays showed that the purified M. tuberculosis 50- to 55-kDa protein was recognized by serum specimens from 70% of individuals with pulmonary tuberculosis from a total of 77 Mexican patients examined.
