Design and application of an easy to use oligonucleotide mass calculation program.
Article in Journal of the American Society for Mass Spectrometry, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 development of new synthesis procedures, an ever increasing number of chemical modifications can now be incorporated into synthetic oligonucleotides, representing new challenges for analytical chemists to efficiently identify and characterize such molecules. While conventional mass spectrometry (MS) has proven to be a powerful tool to study nucleic acids, new and improved methods and software are now needed to address this emerging challenge. In this report, we describe a simple yet powerful program that affords great flexibility in the calculation of theoretical masses for conventional as well as modified oligonucleotide molecules. This easy to use program can accept input oligonucleotide sequences and then calculate the theoretical mass values for full length products, process impurities, potential metabolites, and gas phase fragments. We intentionally designed this software so that modified nucleotide residues can be incorporated into oligonucleotide sequences, and corresponding mass values can be rapidly calculated. To test the utility of this program, two oligonucleotides that contain a large number of chemical modifications were synthesized. We have analyzed these samples using a Q-TOF mass spectrometer and compared the calculated masses to the observed ones. We found that all of the data matched very well with less than 30 ppm mass errors, well within the expectation for our instrument operated in its current mode. These data confirmed the validity of calculations performed with this new software.
