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

The purpose of this study is to evaluate allelic association and linkage of 18 adjacent syntenic short tandem repeat (STR) pairs form out of 30 markers located on 12 different autosomes. Linkage disequilibrium was tested by using the unknown gametic phase genotypes and phased haplotypes from 290 unrelated individuals from Chinese Han population. Genetic linkage analysis between syntenic STRs was performed based on 145 two-generation families which involved 628 meioses. The results showed no significant linkage disequilibrium at any STR pairs and independent inheritance between syntenic STR pairs was indicated. Significant linkage (maximum logarithm of odd (LOD) scores >3.0) was found in 6 out of the 18 adjacent syntenic STR pairs (D1S1627-D1S1677, CSF1PO-D5S818, D6S1017-D6S1043, D6S1043-D6S474, D12S391-vWA, and D19S253-D19S433). These significant linkage marker pairs had a genetic distance ranged from 11.94 to 41.33 cM deduced from HapMap. When recombination fractions determined in families were compared to those derived from Kosambi mapping function based on HapMap data, the latter may have an overestimation. In summary, our results demonstrated that product rule included syntenic STRs can be used for unrelated individual profile probability and the recombination fraction based on family data was superior to the estimation from HapMap for kinship analysis.
