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
Effects of the cytoplasmic tail (CT) of human immunodeficiency virus type 1 Env on the process of membrane fusion were investigated. Full-length Env (wild type [WT]) and Env with its CT truncated (DeltaCT) were expressed on cell surfaces, these cells were fused to target cells, and the inhibition of fusion by peptides that prevent Env from folding into a six-helix bundle conformation was measured. For both X4-tropic and R5-tropic Env proteins, DeltaCT induced faster fusion kinetics than did the WT, and peptides were less effective at inhibiting DeltaCT-induced fusion. We tested the hypothesis that the inhibitory peptides were less effective at inhibiting DeltaCT-induced fusion because DeltaCT folds more quickly into a six-helix bundle. Early and late intermediates of WT- and DeltaCT-induced fusion were captured, and the ability of peptides to block fusion when added at the intermediate stages was quantified. When added at the early intermediate, the peptides were still less effective at inhibiting DeltaCT-induced fusion but they were equally effective at preventing WT- and DeltaCT-induced fusion when added at the late intermediate. We conclude that for both X4-tropic and R5-tropic Env proteins, the CT facilitates conformational changes that allow the trimeric coiled coil of prebundles to become optimally exposed. But once Env does favorably expose its coiled coil to inhibitory peptides, the CT hinders subsequent folding into a six-helix bundle. Because of this facilitation of maximal exposure and hindrance of bundle formation, the coiled coil is optimally exposed for a longer time for WT than for DeltaCT. This accounts for the greater peptide inhibition of WT-induced fusion.
