1 · What the graph read from it

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.

2 · The registry

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 single copy psbA genes from the multicellular red alga Antithamnion spec. and the brown alga Ectocarpus siliculosus have been cloned and sequenced and monocistronic transcripts have been detected. Both genes contain an insertion of 21 bp at the 3' end which was also found in cyanobacteria and which is absent in chloroplasts and the chlorophyll b-containing prochlorophyte Prochlorothrix hollandica. These findings are in agreement with the hypothesis of a polyphyletic origin of plastids. Plastids of red and brown algae appear to be closely related.
