Implication of long-distance cytoplasmic transport into dynamics of local pH on the surface of microinjured Chara cells.
Article in Protoplasma, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Cytoplasmic streaming is essential for intracellular communications but its specific functions are not well known. In Chara corallina internodes, long-distance interactions mediated by cyclosis are clearly evident with microscopy-pulse amplitude modulation (PAM) fluorometer under application of localized light (LL) pulses to a remote cell region. Measurements of LL-induced profiles of chlorophyll fluorescence F' at various distances from the LL source suggest that illuminated chloroplasts release into the streaming cytoplasm excess reducing equivalents that are entrained by the fluid flow and transiently reduce the intersystem electron carriers in chloroplasts of downstream shaded areas. The reducing equivalents propagate to distances up to 4.5 mm from the LL source, with the transport rate nearly equal to the velocity of liquid flow. The F' transients disappeared after the arrest of streaming with cytochalasin D and reappeared upon its recovery in washed cells. The F' responses to a distant LL were used as an indicator for the passage of cytosolic reductants across the analyzed cell area during measurements of cell surface pH (pH
