A localized pattern photobleaching method for the concurrent analysis of rapid and slow diffusion processes.
Article in Biophysical journal, 1983. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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 scanning pattern photobleaching method for the analysis of lateral transport is described and discussed. Fluorescence bleaching with a localized pattern allows for the concurrent analysis of motions over two very different characteristic distances: xi 0(-1), the repeat distance of the pattern, and W, the linear dimension of the illuminated region. The former motion is deduced from the decay of the modulation amplitude (of period xi 0(-1) of fluorescence scans with the attenuated pattern, the latter from the recovery of the average fluorescence intensity. Such analysis should prove useful for the study of samples with a wide range of diffusion coefficients, and for the separation of effects arising from lateral diffusion and association dynamics. Theoretical analyses are presented for three related problems: (a) the effect of pattern localization on the decay of the modulation amplitude, (b) the effect of the pattern modulation on the recovery of the average local fluorescence intensity, and (c) the effect of a limited diffusion space (with linear dimensions of only a few pattern periods) on the decay of the modulation amplitude.
