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

In this study, we explore the effect of a library of 2'-, 4'-, and 2',4'-modified uridine nucleosides and their impact on silencing firefly luciferase and on down-regulated in renal cell carcinoma (DRR) gene targets. The modifications studied were 2'-F-ribose, 2'-F-arabinose, 2'-OMe-ribose, 2'-F,4'-OMe-ribose, 2'-F,4'-OMe-arabinose, and 2'-OMe,4'-F-ribose. We found that 2',4'-modifications are well tolerated within A-form RNA duplexes, leading to virtually no change in melting temperature as assessed by UV thermal melting. The impact of the dual (2',4') modification was assessed by comparing gene silencing ability to 2'- or 4'- (singly) modified siRNA counterparts. siRNAs with (2',4')-modified overhangs generally outperformed the native siRNA as well as siRNAs with a 2'- or 4'-modified overhang, suggesting that 2',4'-modified nucleotides interact favorably with Argonaute protein's PAZ domain. Among the most active siRNAs were those with 2'-F,4'-OMe-ribose or 2'-F,4'-OMe-arabinose at the overhangs. When modifications were placed at
