Trinucleotide repeats as bait for vectorette PCR: a tool for developing genetic mapping markers.
Article in Molecular biotechnology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Trinucleotide repeats are common within gene coding regions and could serve as beacons to locate genes. Five of the most common trinucleotide repeats in an Actinidia (kiwifruit) expressed sequence tag (EST) database were found to be (ACC)(4), (CAC)(4), (CCA)(4), (CTC)(4), and (TGG)(4). These repeats, with or without an artificial 5'-end tail, were tested by vectorette PCR against genomic DNA from Actinidia chinensis. Eighty-nine randomly selected clones showed an average insert size of 383 bp, with a maximum of 1,151 bp and a minimum of 78 bp. Two-thirds of the clones contained the artificial tail attached to the trinucleotide, showing a slight advantage of possessing such a tail during annealing and amplification. The sequences were searched against the Actinidia EST database and GenBank. Of the 89 clones, 33 had a significant hit (expect value < e(-15)). Twenty-four of those clones matched an Actinidia EST. Twenty-one clones contained one or more simple sequence repeats. This methodology can be applied by conventional cloning and sequencing methods or by high throughput pyrosequencing technologies to develop genetic markers and also for gene mining in species with little or no genetic/genomic resources.
