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
Monosaccharide transporter (MST) genes of Lupinus polyphyllus and L. albus were cloned, expressed and characterised. The isolation and functional characterisation of a cDNA clone and its corresponding genomic clone of a sugar transporter from L. polyphyllus (LpSTP1) is reported. Phylogenetic comparison of the nucleic and amino acid sequences showed the highest similarity to the AtSTP1 gene from Arabidopsis thaliana, which encodes a high affinity sugar transporter. The similar topology as well as the substrate specificity and expression pattern of LpSTP1 encoded protein additionally support the high similarity to the AtSTP1 gene product. The 1,590 bp LpSTP1 cDNA clone was heterologously expressed in yeast resulting in a fully functional specific sugar transporter. This transformation restored the viability of a yeast deletion mutant, which is devoid of all intrinsic MSTs and thus unable to take up and grow on hexose-containing media. The LpSTP1 protein is postulated to be a high-affinity MST since it supported growth best on media containing 0.2% hexose. Tissue-specific expression of LaSTP1 in L. albus was assayed by real-time PCR, which revealed that the lupin STP1 is mainly expressed in flower buds, flowers and young leaves. The results suggest that the main role of LaSTP1 is to catalyse monosaccharide import in sink tissues to meet increased carbohydrate demand during plant development.
