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
A total of 2 548 unrelated healthy father-son pairs from a Northern Han Chinese population were genotyped at 41 Y chromosomal short tandem repeat (Y-STRs) including DYS19, DYS388, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS444, DYS447, DYS448, DYS449, DYS456, DYS458, DYS460, DYS481, DYS518, DYS522, DYS549, DYS533, DYS557, DYS570, DYS576, DYS593, DYS596, DYS627, DYS635, DYS643, DYS645, Y-GATA-H4, DYF387S1a/b, DYF404S1a/b, DYS385a/b, and DYS527a/b. In 2 548 father samples, 2 387 unique haplotypes were detected with the haplotype diversity and discrimination capacity values of 0.999 956 608 and 0.96 741 007. The average gene diversity (GD) value was 0.6934 with a range from 0.1051 at DYS645 to 0.9657 at DYS385a/b. When comparing alleles at 24 overlapped Y-STRs between the ForenSeq™ deoxyribonucleic acid (DNA) Signature Prep Kit on the MiSeq FGx® Forensic Genomics System and the Goldeneye® DNA ID Y Plus Kit on the Applied Biosystems™ 3730 DNA Analyzer from 308 father samples in mutational pairs, 258 alleles were detected by massively parallel sequencing (MPS) typing including 156 length-based alleles that could be obtained by capillary electrophoresis (CE) typing, 95 repeat region (RR) variant alleles and seven flanking region variant alleles. Hereof, we found 16 novel RR variant alleles and firstly identified two SNPs (rs2016239814 at DYS19 and rs2089968964 at DYS448) and one 4-bp deletion (rs2053269960 at DYS439) that had been validated by the Database of Short Genetic Variation. Sanger sequencing or MPS was employed to confirm 356 mutations from 104 468 allele transfers generated from CE, where 96.63% resulted in one-step mutations, 2.25% in two-step, and 1.12% in multi-step, and the overall ratio of repeat gains Key points: 308 of 2 548 father-son pairs from Northern Han Chinese occurred at least one mutation(s) across 41 Y-STRs.Sanger sequencing or MPS was employed to confirm those mutations generated from CE.The longer STR region, the more complex motif and the order father drove Y-STR mutation rates increased.StatsY was developed to calculate allele and haplotype frequencies, forensic parameters and mutation rates at Y-STRs.
