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
Dysfunctional mitochondria are implicated in various diseases, but comprehensive characterization of mitochondrial DNA (mtDNA) in the Chinese population remains limited. Here, we conducted a systematic analysis of mtDNA from 7331 samples, comprising 4129 Chinese samples from the NyuWa cohort and 3202 samples from the 1000 Genomes Project (1KGP). We identified 7216 high-quality mtDNA variants, which classified 7266 samples into 22 macro-haplogroups, and detected 1466 nuclear mitochondrial DNA segments (NUMTs). Among these, 88 mtDNA variants and 642 NUMTs were specific to NyuWa. Genome-wide association analyses revealed significant correlations between 12 mtDNA variants and 199 nuclear DNA (nDNA) variants. Our findings demonstrated that all individuals in both NyuWa and 1KGP harbored common NUMTs, while one-fifth possessed ultra-rare NUMTs that tended to insert into nuclear gene regions. Notably, rare NUMTs in the NyuWa cohort showed significant enrichment of nuclear breakpoints in long interspersed nuclear elements (LINEs) compared to 1KGP. Overall, this study provides the first comprehensive profile of NUMTs in the Chinese population and establishes the most extensive resource of Chinese mtDNA variants and NUMTs to date based on high-depth whole-genome sequencing, providing valuable reference resources for genetic research on mtDNA-related diseases.
