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
Antisense oligonucleotides (ASOs) are becoming a promising class of drugs for treating various diseases. Over the past few decades, many modified nucleic acids have been developed for application to ASOs, aiming to enhance their duplex-forming ability toward cognate mRNA and improve their stability against enzymatic degradations. Modulating the sugar conformation of nucleic acids by substituting an electron-withdrawing group at the 2'-position or incorporating a 2',4'-bridging structure is a common approach for enhancing duplex-forming ability. Here, we report on incorporating an N-tert-butylguanidinium group at the 2',4'-bridging structure, which greatly enhances duplex-forming ability because of its interactions with the minor groove. Our results indicated that hydrophobic substituents fitting the grooves of duplexes also have great potential to increase duplex-forming ability.
