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 the sequences released by the Arabidopsis Genome Initiative (AGI), we discovered a new and unexpectedly large family of orphan genes (127 genes by 01.08.99), named AtPCMP. The distribution of the AtPCMP genes on the five chromosomes suggests that the genome of Arabidopsis thaliana contains more than 200 genes of this family (1% of the whole genome). The deduced AtPCMP proteins are characterized by a surprising combinatorial organization of sequence motifs. The amino-terminal domain is made of a succession of three conserved motifs which generate an important diversity. These proteins are classified into three subfamilies based on the length and nature of their carboxy-terminal domain constituted by 1-6 motifs. All the motifs characterized have an important level of conservation in both sequence and spacing. A specific signature of this large family is defined. The presence of ESTs in databases and the detection of clones in A. thaliana cDNA libraries indicate that most of the genes of this family are expressed. The absence of similar sequences outside the plant kingdom strongly suggests that this unusually large orphan family is unique to plants. Features, the genesis, the potential function and the evolution of this plant combinatorial and modular protein family are discussed.
