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

Previous cytological analysis of heterochromatic rearrangements has yielded significant insight into the location and genetic organization of genes mapping to the heterochromatin of chromosomes X, Y, and 2 of Drosophila melanogaster. These studies have greatly facilitated our understanding of the genetic organization of heterochromatic genes. In contrast, the 12 essential genes known to exist within the mitotic heterochromatin of chromosome 3 have remained only imprecisely mapped. As a further step toward establishing a complete map of the heterochomatic genetic functions in Drosophila, we have characterized several rearrangements of chromosome 3 by using banding techniques at the level of mitotic chromosome. Most of the rearrangement breakpoints were located in the dull fluorescent regions h49, h51, and h58, suggesting that these regions correspond to heterochromatic hotspots for rearrangements. We were able to construct a detailed cytogenetic map of chromosome 3 heterochromatin that includes all of the known vital genes. At least 7 genes of the left arm (from l(3)80Fd to l(3)80Fj) map to segment h49-h51, while the most distal genes (from l(3)80Fa to l(3)80Fc) lie within the h47-h49 portion. The two right arm essential genes, l(3)81Fa and l(3)81Fb, are both located within the distal h58 segment. Intriguingly, a major part of chromosome 3 heterochromatin was found to be "empty," in that it did not contain either known genes or known satellite DNAs.
