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

Conjugation of anticancer drugs to hydrophilic peptides such as Tat is a widely adopted strategy to improve the drug's solubility, cellular uptake, and potency against cancerous cells. Here we report that attachment of an anticancer drug doxorubicin to the N- or C-terminal of the Tat peptide can have a significant impact on their cellular uptake and cytotoxicity against both drug-sensitive and drug-resistant cancer cells. We observed higher cellular uptake by both cell lines for C-terminal conjugate relative to the N-terminal analogue. Our results reveal that the C-terminal conjugate partially overcame the multidrug resistance of cervical cancer cells, while the N-terminal conjugate showed no significant improvement in cytotoxicity when compared with free doxorubicin. We also found that both N- and C-conjugates offer a mechanism to circumvent drug efflux associated with multidrug resistance.
