The purification of a 50 kDa protein-actin complex from unfertilized sea-urchin (Strongylocentrotus purpuratus) eggs.
Article in The Biochemical journal, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 100,000 g supernatant from the unfertilized egg of the sea urchin Strongylocentrotus purpuratus has been fractionated on DEAE-cellulose and analysed for Ca2+-binding activity by the Chelex-100 competitive Ca2+-binding activity assay. The major peak of Ca2+-binding activity was subjected to further purification and the Ca2+-binding protein responsible for this Ca2+-binding-activity peak has been isolated and characterized. Non-denaturing polyacrylamide-gel electrophoresis (PAGE) followed by 45Ca2+ autoradiography suggested a molecular mass of 80 kDa for the Ca2+-binding protein. SDS/PAGE revealed that the 80 kDa protein consisted of a 1:1 molar complex of proteins of 50 and 42 kDa. The 42 kDa protein was identified as actin. The complex was not dissociated by extensive dialysis against an EGTA-containing buffer. The EGTA-stable complex was named '50K-A'.
