Limit of the Accuracy of Parameter Estimation for Two Molecules Moving in Close Proximity.
Article in IEEE International Symposium on Circuits and Systems proceedings. IEEE International Symposium on Circuits and Systems, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Biomolecular interactions are central to biological processes and typically take place at nanometer scale distances. They often involve molecular motion which is known to affect the accuracy of the parameter estimates. Therefore, in this paper, we consider a case of two closely spaced molecules with planar trajectory and present a general expression of the Fisher information matrix in terms of their trajectory from which the benchmark for the accuracy of the parameter estimates is obtained. Through simulations, we show its application in the case of two moving objects and another case where only one of the two objects is moving. It is shown that the deterioration of the limit of the accuracy is not only dependent on the proximity of their starting position but also on their speed and direction of movement. The effect of differing photon emission intensities on the limit of the accuracy of parameter estimation is also investigated.
