Evaluation of different conditions for ligating dumbbell-shaped oligonucleotides.
Article in Molecular biotechnology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
We tested three different standard ligation conditions (37 degrees C for 30 min, 16 degrees C for 24 h, and 4 degrees C for 48 h) to generate dumbbell-shaped oligonucleotides (ODNs) as transcription factor decoys for SOX9 and alphaA-crystallin binding protein 1 (CRYBP1), which are positive and negative transcriptional regulators for type II collagen expression in chondrocytes. Decoy ODN for CRYBP1 was successfully produced as a "dumbbell" by all three conditions. A small amount of decoy ODN for SOX9, however, remained unligated under all three ligation conditions. Ligation at 4 degrees C for 48 h appeared to be the least desirable for SOX9 ODN. Transfection experiments with the SOX9 ODN ligated in different conditions and a luciferase-based reporter system also supports this conclusion. In general, shorter incubation time produced more acceptable results for this ODN than incubation for a longer time. These data suggest that different ligation conditions should be tested prior to creating dumbbell-shaped ODNs for transfection experiments.
