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

Background: nbalanced translocations can cause developmental delay, intellectual disability, growth problems, dysmorphic features, and congenital anomalies Unbalanced chromosome rearrangements that are cytogenetically visible account for ~3% of all recognized chromosome abnormalities. A lot of unbalanced translocations have been reported. Objective: Here, we present an individual who has an unbalanced translocation caused by deletion of the terminal region of chromosome 5p encompassing 170 kb coupled with a 11.4 Mb duplication of the terminal region of chromosome 18q.. Case presentatioin: We report the first case of unbalanced translocation in a phenotypically normal male after performing clinical phenotyping, cytogenetic analyses and then array-comparative genomic hybridization after detection of unbalanced translocation in his fetus. Conventional G-banded karyotyping showed additional chromatin of unknown origin on the long arm of chromosome 5: 46,XX,add(5)(p15.3). The microarray result confirmed an unbalanced translocation with the loss of ~170kb of chromosome 5p and duplication of 11.4Mb of the long arm of chromosome 18 (arr[GRCh37]5p15.33(22149_192836)x1, 18q22.1q23(66590438_78012829)x3 of a normal adult. Conclusion: This is the first time we found the unbalanced translocation in a totally healthy man to our knowledge. Therefore, the karyotypes of the parents should be indicated whenever the unbalanced translocation detected in a fetus to have more data for prognosis.
