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
We have isolated a cDNA clone, OsFOR1, from the immature panicles of rice. The OsFOR1 (Oryza sativa floral organ regulator 1) gene encodes a protein that contains a leucine-rich repeat (LRR) domain. This domain comprises 10 tandem repeats of a canonical 24-amino acid LRR sequence. The structure and the number of LRRs for OsFOR1 are similar to those of polygalacturonase-inhibiting proteins (PGIPs) from various other plant species. Moreover, the OsFOR1 recombinant protein, when fused to maltose-binding protein (MBP), shows PGIP activity against the Aspergillus niger polygalacturonase. OsFOR1 is highly expressed in the calli and immature and mature panicles, while detectable at only low levels in seedling roots and mature stems. In situ hybridization experiments showed the transcripts of OsFOR1 are present in young spikelet primordia and in almost all of the young floral organs. Transgenic approaches were used to study in vivo functioning. Antisense expression of OsFOR1 resulted in an increase in the numbers of floral organs, including the stamen, carpel, palea/lemma, stigma, and lodicule. OsFOR1 transcript was not detected in the frizzy panicle mutant, which is defective in its spikelet formation but normal in inflorescence-meristem initiation and maintenance. Therefore, we suggest that OsFOR1 plays a role in the formation and/or maintenance of floral organ primordia.
