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 genome of Pneumocystis, which causes life-threatening pneumonia in immunosuppressed patients, contains a multicopy gene family that encodes the major surface glycoprotein (Msg). Pneumocystis can vary the expressed Msg, presumably as a mechanism to avoid host immune responses. Analysis of 24 msg-gene sequences obtained from a single human isolate of Pneumocystis demonstrated that the sequences segregate into 2 branches. Results of a number of analyses suggest that recombination between msg genes is an important mechanism for generating msg diversity. Intrabranch recombination occurred more frequently than interbranch recombination. Restriction-fragment length polymorphism analysis of human isolates of Pneumocystis demonstrated substantial variation in the repertoire of the msg-gene family, variation that was not observed in laboratory isolates of Pneumocystis in rats or mice; this may be the result of examining outbred versus captive populations. Increased diversity in the Msg repertoire, generated in part by recombination, increases the potential for antigenic variation in this abundant surface protein.
