MS/MS of ions in a low pressure linear ion trap using a pulsed gas.
Article in Journal of the American Society for Mass Spectrometry, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
A pulsed valve was used to increase the pressure within the trapping region of a low-pressure linear ion trap by situating the pulsed valve close to the ion trapping region. The pressure was estimated to increase from a background pressure of 3.5e-5 Torr of nitrogen to 0.49 mTorr at the center of the trap. The increased pressure allowed excitation periods to be reduced from 100 to 25 ms without suffering losses in MS/MS efficiency during dipolar excitation. The reduction in excitation period translates into an increase in the overall duty cycle of the scan.
