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 multidirectional bioactivity of betulin (BN), its widespread occurrence in plants, relatively low toxicity, and acceptable safety profile make it an attractive scaffold for scientific research and potential therapeutic applications. Due to the presence of reactive functional groups (C-3-OH and C-28-OH), BN is an interesting source of new semisynthetic bioactive compounds obtained via structural modifications of the parent backbone. In our study, we designed new BN-amino acid (BNAA) molecular hybrids, aiming to exploit synergistically the properties of both components. We prepared and evaluated a total of 18 new compounds for antitumor activity against the two human cancer cell lines (HCT 116 and MCF-7) and one non-cancerous cell line (NHDF) using a standard Cell Counting Kit-8 (CCK-8) assay. The potential signaling pathways of the obtained BN derivatives were identified based on the measurement of p21 and Bax mRNA expression levels using the RT-qPCR method. We successfully synthesized a series of new BN hybrids by conjugation of the C-3 and C-28 hydroxyl groups
