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
Epistasis is considered to be a primary genetic basis of hybrid breakdown. We found novel epistatic genes causing hybrid breakdown in an intraspecific cross of cultivated rice (Oryza sativa L.). F2 progeny derived from a cross between a Japonica variety, Asominori, and an Indica variety, IR24, showed segregation of high sterility for seeds, even though the reciprocal F1 hybrids showed about 60% seed fertility. Backcross populations (BC3F2, BC3F3), obtained from repeated backcrossing with Asominori, showed the segregation of causal genes in a simple Mendelian fashion. Using these populations, we identified that this sterility was hybrid breakdown caused by interaction among three nuclear genes distributed on the both parental genomes. These new genes, designated as hsa1, hsa2, and hsa3, were found to be involved in female gamete development by histological examination. The Indica parent IR24 has a sterile allele, hsa1-IR, which was located at near RFLP marker G148 on chromosome 12, whereas the Japonica parent Asominori has two sterile alleles, hsa2-As on chromosome 8 (close to G104) and hsa3-As on chromosome 9 (close to RM285). Female gametes carrying the hsa1-IR, hsa2-As, and hsa3-As alleles aborted in hsa1-IR homozygous plant, leading to seed sterility and selective elimination of the specific allelic combination. This study provides direct evidence that hybrid breakdown is attributed to epistatic interaction of genes from both parents and suggests that complicated mechanisms has been developed for hybrid breakdown during the evolution of rice.
