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

This study presents the first investigation of acetyl-11-keto-β-boswellic acid (AKBA)'s anti-human cytomegalovirus (HCMV) activity in vitro and elucidates its underlying mechanisms. In HCMV Towne strain-infected WI-38 cells, AKBA (1-12 μM) exhibited negligible cytotoxicity while significantly suppressing virus-induced cytopathic effects (CPE) at 6-10 μM, with dose-dependent reduction of viral proteins (IE1/2 and p52) expression, viral DNA copy number (UL123, UL44, and UL32), and infectious viral progeny titer (TCID50). Time-of-addition experiments demonstrated the primary antiviral activity of AKBA during post-entry phase, along with direct virion inactivation. Transcriptome analysis revealed that AKBA significantly downregulated the expression of the host factor NR4A1 induced by HCMV, a finding further validated by Western blotting. Further gene knockdown experiments confirmed that silencing NR4A1 significantly reduced the expression of viral proteins IE1/2, thereby validating NR4A1 as a key host factor for HCMV infection. These findings indicate that AKBA has a potent and dose-dependent inhibitory effect on HCMV replication in WI-38 cells, and proves that this effect is mediated through two different mechanisms: one is the downregulation of the expression of the key host factor NR4A1, and the other is the direct inactivation of HCMV viral particles.
