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 cDNAs CnHAK1 and CnHAK2, encoding K+ transporters, were amplified from the leaves of the seagrass Cymodocea nodosa. None of these transporters suppressed the K+ deficiency of a Saccharomyces cerevisiae mutant, but both suppressed the equivalent defect of an Escherichia coli mutant. Overexpression of the transporter CnHAKI, but not CnHAK2, mediated very rapid K+ or Rb+ influxes in the E. coli mutant. The concentration dependence of these influxes demonstrated that CnHAK1 is a low-affinity K+ transporter, which does not discriminate between K+ and Rb+. CnHAK1 expressed in E. coli worked in reverse when the external K+ concentrations were low, and we established the condition of a simple functional test of K+ loss for transporters of the Kup-HAK family. In comparison with its homologue barley transporter HvHAK2, CnHAKI was insensitive to Na+.
