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

We isolated and molecularly cloned a human immunodeficiency virus type 1 (HIV-1) strain (89.6) which is unusual because it is both macrophage-tropic and extremely cytopathic in lymphocytes. Moreover, this is the first well-characterized infectious molecularly cloned macrophage-tropic HIV-1 strain derived from peripheral blood. HIV-1 89.6 differs markedly from other macrophage-tropic isolates within the envelope V3 region, which is important in determining cell tropism and cytopathicity. HIV-1 89.6 may thus represent a transitional isolate between noncytopathic macrophage-tropic viruses and cytopathic lymphocyte-tropic viruses.
