1 · What the graph read from it

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.

2 · The registry

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

Acrocomia aculeata (macaúba) is an oil-producing palm with high potential for sustainable bioenergy in tropical regions. We present the first chromosome-scale, haplotype-resolved genome assembly for the species and the genus, generated with Oxford Nanopore, PacBio HiFi, and Hi-C sequencing. The assembly spans 1.94 Gbp organized into 15 pseudochromosomes (N50 = 143.43 Mbp; QV = 76.4), with two fully phased haplotypes (Hap1: 1.93 Gbp; Hap2: 1.92 Gbp) resolved at chromosome scale. Genome completeness reached 98.9% complete BUSCOs for predicted proteins and > 90% k-mer completeness. Repetitive elements comprise 73-77% of the genome, with LTR retrotransposons accounting for ~55%. The LTR Assembly Index (LAI = 25.11) confirms gold-standard quality, sustained across both haplotypes. Annotation predicted 28,367 protein-coding genes with structural consistency across haplotypes and similarity to other palm genomes. Comparative analyses revealed strong chromosomal collinearity with closely related species. This reference genome supports evolutionary genomics, conservation, and molecular breeding of macaúba.
