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
Differences in knotted1-like (knox) gene expression may account for some of the diversity of leaf forms seen in nature. Class 1 knox genes are expressed in the compound leaf primordia of tomato but not in the simple leaf primordia of a range of species examined so far. In order to test the hypothesis that all compound leaves differ from simple leaves in this way, we isolated a class 1 knox cDNA from pea, Pskn1 (Pisum sativum knotted1) and examined its expression pattern. The encoded homeodomain of Pskn1 shares 88% identical residues with KNOTTED1 from maize and an adjacent ELK domain is present. The protein sequence of PSKN1 is 69% identical to TKN2, its nearest related sequence in tomato. Unlike TKn2, Pskn1 was not expressed in newly initiated compound leaves. The expression pattern of Pskn1 resembled those of other class 1 knox genes described in maize and Arabidopsis. Transcripts were detected in the shoot apical meristem and developing vasculature of the vegetative shoot, but expression was not detected in newly initiated and developing compound leaf primordia. The same pattern of expression was observed in the afila mutant, which is characterised by highly ramified compound leaves. Our results suggest that tomato and pea use different developmental processes in the generation of their compound leaves.
