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

backgroundSphagnum L. (peat mosses) comprises approximately 291 recognized species distributed worldwide except Antarctica. Plastomes are useful for investigating structure evolution and phylogeny due to their conserved structure. However, Sphagnum species endemic to China have been underrepresented in plastome-based studies, hindering a comprehensive understanding of their evolutionary history.

resultsAnalysis of 13 plastomes of eight Sphagnum species from China, revealed both inter-and intraspecific variations. Plastome sizes ranged from 138,958 bp (S. acutifolioides) to 141,257 bp (S. ovatum), with conserved gene content (86 CDSs, 37 tRNAs, 8 rRNAs). All plastomes exhibited a typical quadripartite structure: LSC (96,896-99,205 bp), SSC (21,187-21,381 bp), and IRs (10,298-10,391 bp). The IR boundaries and adjacent genes were consistent, except in S. squarrosum, where chIL entered IRb and ndhF entered IRa. Premature termination of the petN gene was detected in all species except S. medium and S. palustre (population: GZ and HB). Codons with RSCU > 1.00 favored A/U at the third position, with UUA (Leucine) and GCU (Alanine) being most common. SSRs dominated by mono- and di-repeats, with tri-repeats were highly conserved. Phylogenetic analysis supported the placement of S. ovatum, S. subsecundum, and S. acutifolioides in subgenus Subsecunda; S. medium and S. palustre in subgenus Sphagnum; and S. warnstorfii, S. fuscum, and S. squarrosum in subgenus Acutifolia.

conclusionDespite overall structural conservation, expanded sampling revealed both inter- and intraspecific plastome variation in Sphagnum, underscoring the utility of plastomes for phylogenetic inference and assessing genetic diversity. These findings enhance our understanding of Chinese Sphagnum species and their evolutionary relationships.
