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
Multidimensional ion mobility spectrometry coupled with mass spectrometry (IMS-IMS-MS) techniques are used to select and activate six different gas-phase conformations of bradykinin [M + 3H](3+) ions. Drift time distributions as a function of activation voltage show that at low voltages selected structures undergo conformational transitions in what appears to be a pathway dependent fashion. Over a relatively wide range of intermediate activation voltages a distribution of states that is independent of the initial conformation selected for activation (as well as the activation voltage in this intermediate region) is established. This distribution appears to represent an equilibrium distribution of gas-phase structures that is reached prior to the energy required for dissociation. Establishment of a quasi-equilibrium prior to dissociation results in identical dissociation patterns for different selected conformations. A discussion of the transition from solution-like to gas-phase structures is provided.
