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

The argan tree (Argania spinosa), endemic to Morocco, holds major ecological and economic value. We generated a high-quality, chromosome-scale, phased reference genome using PacBio HiFi long reads and Hi-C scaffolding. The assembly resolves two haplotypes, each organized into 11 pseudochromosomes (2n = 22). Haplotype-1 spans 621 Mb (scaffold N50 = 50 Mb; GC = 33.79%), and Haplotype-2 spans 615 Mb (scaffold N50 = 51 Mb; GC = 33.77%). BUSCO completeness is 97.8% for Hap1 and 98.1% for Hap2, with Merqury QV values of 75 for both, indicating high consensus accuracy and strong phasing. Telomeric repeats (AAACCCT)n appear at both ends of most chromosomes, and only small terminal gaps remain, so we conservatively classify the assemblies as near-T2T. We annotated 35,183 gene loci producing 39,805 mRNA isoforms and 410 tRNA genes, with 76.46% of loci functionally characterized. Repeats represent 61.65% of the genome, dominated by LTR retrotransposons. All raw data, assemblies, and annotations are publicly accessible, providing a robust genomic foundation for conservation genetics, breeding, and evolutionary studies in A. spinosa.
