Evening primrose oil and olive oil in treatment of rheumatoid arthritis.
Article in Clinical rheumatology, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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 effects of 10 ml of evening primrose oil or olive oil, administered twice daily for 12 weeks, on clinical and laboratory signs and on plasma prostaglandins were studied in 18 patients with rheumatoid arthritis. The plasma concentration of PGE2 decreased and that of TxB2 increased in both treatment groups, but no significant improvement could be seen in either group.
