Posttranslational modifications of tubulin in teleost photoreceptor cytoskeletons.
Article in Cellular and molecular neurobiology, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
1. Posttranslational modifications of tubulin by acetylation and detyrosination have been correlated previously with microtubule stability in numerous cell types. 2. In this study, posttranslational modifications of tubulin and their regional distribution within teleost photoreceptor cones and rods are demonstrated immunohistochemically using antibodies specific for acetylated, detyrosinated, or tyrosinated tubulin. 3. Immunolocalization was carried out on isolated whole cones and mechanically detached rod and cone inner/outer segments. 4. Acetylated tubulin within rods and cones is found only in microtubules of the ciliary axoneme of the outer segment. Detyrosinated tubulin is also enriched in axonemes of both rod and cone outer segments. 5. Distributions of tyrosinated and detyrosinated cytoplasmic microtubules differ within cones and rods. In cones, detyrosinated and tyrosinated tubulins are both abundant throughout the cell body. In rods, the ellipsoid and myoid contain much more tyrosinated tubulin than detyrosinated tubulin. Comparisons between whole cones and cone fragments suggest that detyrosinated microtubules are more stable than tyrosinated microtubules in teleost photoreceptors. 6. Our findings provide further evidence that microtubules of teleost cones differ from rod microtubules in their stabilities and rapidity of turnover within the photoreceptor inner segment.
