In Situ Pressure Probe Sampling and UV-MALDI MS for Profiling Metabolites in Living Single Cells.
Review in Mass spectrometry (Tokyo, Japan), 2012. 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
In this work we describe the use of a combination of a cell pressure probe and a UV-matrix-assisted laser desorption/ionization time of flight (UV-MALDI-TOF) mass spectrometer for the in situ picoliter sampling and shotgun metabolite profiling of living single cells of plants. In addition to quantifiable sampling, the pressure probe has some unique features which differentiate it from other single-cell analytical tools. Cell wall and plasma membrane properties and water relations of in situ living single cells can be analyzed before sampling the cell sap. In addition, the fully-controlled sampling of cells located at different depths in plant tissues, measurement of the sample volume, and the addition of internal standards are facilitated by the pressure probe. Using a variety of organic compounds and nanoparticles as UV-MALDI matrices, metabolites from neutral carbohydrates to amino acids and other metabolites can be detected through UV-MALDI-TOF mass spectrometry analyses of picoliter-sized, single-cell samples.
