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 high-resolution physical map targeting a cluster of yield-related QTLs on the long arm of rice chromosome 9 has been constructed across a 37.4 kb region containing seven predicted genes. Using a series of BC3F4 nearly isogenic lines (NILs) derived from a cross between the Korean japonica cultivar Hwaseongbyeo and Oryza rufipogon (IRGC 105491), a total of seven QTLs for 1,000-grain weight, spikelets per panicle, grains per panicle, panicle length, spikelet density, heading date and plant height were identified in the cluster (P<or=0.0001). All seven QTLs were additive, and alleles from the low-yielding O. rufipogon parent were beneficial in the Hwaseongbyeo background. Yield trials with BC3F4 NILs showed that lines containing a homozygous O. rufipogon introgression in the target region out-yielded sibling NILs containing Hwaseongbyeo DNA by 14.2-17.7%, and out-yielded the Hwaseongbyeo parent by 16.2-23.7%. While higher yielding plants containing the O. rufipogon introgression were also taller and later than controls, the fact that all seven of the QTLs were co-localized in the same 37.4 kb interval suggests the possibility that a single, pleiotropic gene acting as a major regulator of plant development may control this suite of agronomically important plant phenotypes.
