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
A genomic clone, pWS44, isolated from the chicken W chromosome-specific genomic library contained a partial (226-bp) sequence of a novel SspI-family repetitive sequence. A genomic clone, pWPRS09, containing a 508-bp SspI fragment (a repeating unit of the family) was subsequently obtained and sequenced. This 0.5-kb unit is tandemly repeated about 11,300 times. FISH to mitotic and lampbrush W chromosomes indicates that the SspI-family is located on the chromomere 6 between heterochromatic and distal non-heterochromatic regions on the short arm. The SspI-family sequence was proved to be a good positional marker in FISH mapping of active genes in the non-heterochromatic region on the lampbrush W chromosome. The presence of SspI-family repetitive sequence is limited to the genus Gallus (chickens and jungle fowls). The 0.5-kb repeating unit contains a 120-bp stretch of polypurine/polypyrimidine sequence (GGAGA repeats), shows no DNA curvature, and rapid electrophoretic mobility in 4% polyacrylamide gel at 4 degrees C. The SspI-family forms a relatively diffused chromatin structure in nuclei. These features are distinctly different from those of XhoI- and EcoRI-family sequences on the W chromosome. The total amount of non-repetitive DNA in the chicken W chromosome is estimated to be about 10 Mb.
