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
In rice (Oryza sativa), a short-day plant, photoperiod is the most favorable external signal for floral induction because of the constant seasonal change throughout the years. Compared with Arabidopsis, however, a large part of the regulation mechanism of the photoperiodic response in rice still remains unclear due mainly to the lack of induced mutant genes. An induced mutant line X61 flowers 35 days earlier than its original variety Gimbozu under a natural photoperiod in Kyoto (35°01'N). We attempted to identify the mutant gene conferring early heading to X61. Experimental results showed that the early heading of X61 was conferred by a complete loss of photoperiodic response due to a novel single recessive mutant gene se13. This locus interacts with two crucial photoperiod sensitivity loci, Se1 and E1. Wild type alleles at these two loci do not function in coexistence with se13 in a homozygous state, suggesting that Se13 is an upstream locus of the Se1 and E1 loci. Linkage analysis showed that Se13 is located in a 110 kb region between the two markers, INDEL3735_1 and INDEL3735_3 on chromosome 1. A database search suggested that the Se13 gene is identical to AK101395 (=OsHY2), which encodes phytochromobilin synthase, a key enzyme in phytochrome chromophore biosynthesis. Subsequent sequence analysis revealed that X61 harbors a 1 bp insertion in exon 1 of OsHY2, which induces a frame-shift mutation producing a premature stop codon. It is therefore considered that the complete loss of photoperiodic response of X61 is caused by a loss of function of the Se13 (OsHY2) gene involved in phytochrome chromophore biosynthesis.
