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
key messageA 14 bp deletion in CsACS2 gene encoding a truncated loss-of-function protein is responsible for elongated fruit shape and perfect flowers in cucumber. In cucumber (Cucumis sativus L.), sex expression and fruit shape are important components of biological and marketable yield. The association of fruit shape and sex expression is a very interesting phenomenon. The sex determination is controlled primarily by the F (female) and M (monoecy) loci. Homozygous recessive mm plants bear bisexual (perfect) flowers, and the fruits are often round shaped. CsACS2 encoding the 1-aminocyclopropane-1-carboxylic acid synthase has been shown to be the candidate gene for the m locus. We recently identified an andromonoecious cucumber line H38 that has bisexual flowers but elongated fruits. To rapidly clone this monoecious gene in H38, we developed a tri-parent mapping strategy, which took advantage of the high-density Gy14 × 9930 cucumber genetic map and the powder of bulk segregant analysis. Microsatellite markers from the Gy14 × 9930 map were used to screen two pairs of unisexual and bisexual bulks constructed from H38 × Gy14 and H38 × 9930 F2 populations. Polymorphic markers were identified and used to quickly develop a framework map and place the monoecious locus of H38 in cucumber chromosome 1. Further fine mapping allowed identification of a novel allele, m-1, at the monoecious locus to control the bisexual flower in H38, which was due to a 14 bp deletion in the third exon of the CsACS2 gene encoding a truncated loss-of-function protein of the cucumber 1-aminocyclopropane-1-carboxylic acid synthase. This new allele provides a valuable tool in understanding the molecular mechanisms of CsACS2 in the relationships of sex determination, fruit shape, and CsACS activities in cucumber.
