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
Severe acute respiratory syndrome (SARS) is an infectious and highly contagious disease that is caused by SARS coronavirus (SARS-CoV) and for which there are currently no approved treatments. We report the discovery and characterization of small-molecule inhibitors of SARS-CoV replication that block viral entry by three different mechanisms. The compounds were discovered by screening a chemical library of compounds for blocking of entry of HIV-1 pseudotyped with SARS-CoV surface glycoprotein S (SARS-S) but not that of HIV-1 pseudotyped with vesicular stomatitis virus surface glycoprotein G (VSV-G). Studies on their mechanisms of action revealed that the compounds act by three distinct mechanisms: (i) SSAA09E2 {N-[[4-(4-methylpiperazin-1-yl)phenyl]methyl]-1,2-oxazole-5-carboxamide} acts through a novel mechanism of action, by blocking early interactions of SARS-S with the receptor for SARS-CoV, angiotensin converting enzyme 2 (ACE2); (ii) SSAA09E1 {[(Z)-1-thiophen-2-ylethylideneamino]thiourea} acts later, by blocking cathepsin L, a host protease required for processing of SARS-S during viral entry; and (iii) SSAA09E3 [N-(9,10-dioxo-9,10-dihydroanthracen-2-yl)benzamide] also acts later and does not affect interactions of SARS-S with ACE2 or the enzymatic functions of cathepsin L but prevents fusion of the viral membrane with the host cellular membrane. Our work demonstrates that there are at least three independent strategies for blocking SARS-CoV entry, validates these mechanisms of inhibition, and introduces promising leads for the development of SARS therapeutics.
