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
With the goal to develop coralyne-based ligands for abasic site-containing DNA (AP-DNA), different synthetic routes towards the functionalization of coralyne were tested. In particular, the alkylation of the benzylic position in papaverine and subsequent cyclization by treatment with acetic anhydride in sulfuric acid led to the synthesis of a coralyne derivative with an alkoxyamine-functionalized linker attached at position C13. Firstly, it was demonstrated with a resembling model compound that the alkylation of the coralyne scaffold does not influence the DNA-binding properties. Furthermore, it was shown that the alkoxyamine function can be readily released from a Boc-protected precursor and that the corresponding coralyne-alkoxyamine conjugate can operate as a ligand for AP-DNA and as inhibitor of enzymatic repair of abasic sites.
