Elemental profiling of single bacterial cells as a function of copper exposure and growth phase.
Article in PloS one, 2011. 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
The elemental composition of single cells of Nitrosomonas europaea 19718 was studied via synchrotron X-ray fluorescence microscopy (XFM) as a function of inhibition by divalent copper (Cu(II)) and batch growth phase. Based on XFM, the intracellular Cu concentrations in exponential phase cultures of N. europaea exposed to Cu(II) were statistically higher than in stationary phase cultures at the 95% confidence interval (α = 0.05). However, the impact of Cu inferred from specific oxygen uptake rate (sOUR) measurements at the two physiological states was statistically not dissimilar at the Cu(II) doses tested, except at 1000 µM Cu(II), at which exponential phase cultures were significantly more inhibited. Furthermore, the elemental composition in uninhibited exponential and stationary phase N. europaea cultures was similar. Notably, the molar fractions of Cu and Fe, relative to other elements in N. europaea cultures were statistically higher than those recently reported in Pseudomonas fluorescens possibly owing to the preponderance of metal cofactor rich catalytic enzymes (such as ammonia monooxygenase) and electron transport mechanisms in N. europaea.
