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
Two starch synthase clones, zSSIIa and zSSIIb, were isolated from a cDNA library constructed from W64A maize endosperm. zSSIIa and zSSIIb are 3124 and 2480 bp in length, and contain open reading frames of 732 and 698 amino acid residues, respectively. The deduced amino acid sequences of the two clones share 58.1% sequence identity. Amino acid sequence identity between the zSSIIa and zSSIIb clones and the starch synthase II clones of potato and pea ranges between 45 to 51%. The predicted amino acid sequence from each SSII cDNA contains the KXGGL consensus motif at the putative ADP-Glc binding site. Both clones also contain putative transit peptides followed by the VRAA(E)A motif, the consensus cleavage site located at the C-terminus of chloroplast transit peptides. The identity of the zSSIIa and zSSIIb clones as starch synthases was confirmed by expression of enzyme activity in Escherichia coli. Genomic DNA blot analysis revealed two copies of zSSIIa and a single copy of zSSIIb. zSSIIa was expressed predominantly in the endosperm, while transcripts for zSSIIb were detected mainly in the leaf at low abundance. These findings establish that the zSSIIa and zSSIIb genes are characteristically distinct from genes encoding granule-bound starch synthase I (Waxy protein) and starch synthase I.
