Comparison of F-actin fluorescent labeling methods in pollen tubes of Lilium davidii.
Article in Plant cell reports, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Fluorescence labeling of F-actin in pollen tubes by various methods has produced inconsistent results in the literature. Here, we report that EGTA, which was always used in fixative buffers in the past and thought to help cytoskeleton stabilization, can significantly affect F-actin distribution and lead to the formation of thick F-actin bundles at the tip of the pollen tube. We also found that vacuum-infiltration for the first 5 min during pollen tube fixation can better preserve normal cytoplasm structure and F-actin distribution. In contrast, m-maleimidobenzoic acid N-hydroxysuccinimide ester (MBS) treatment before chemical fixation resulted in a shortening of the free zone of thick F-actin bundles in the pollen tube tip. Taken together, our results suggest that exclusion of EGTA and MBS from the fixative buffer, in combination with vacuum-infiltration in the first 5 min of fixation, can improve F-actin fluorescence labeling in pollen tubes of Lilium davidii.
