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
backgroundThe common mudskipper (Periophthalmus kalolo Lesson, 1831) belongs to a group of fish species that exhibit amphibious lifestyles during specific daily periods. However, identifying this species poses a challenge due to its morphological similarities with other mudskipper species. These similarities have occasionally caused misidentifications of mudskippers. In Indonesia, previous studies have examined the genetic variation of common mudskippers, but these investigations have been limited to a few specific areas, particularly along the southern coast of Java. As a result, the available data remain fragmented, and no comprehensive genetic population analysis of common mudskippers on the southern coast of Java has been conducted. Therefore, our study aimed to establish DNA barcodes of COI mtDNA and explore the genetic variation and relationship among these common mudskipper populations from the southern coast of Java. We collected nine specimens from two populations, Cilacap Mangrove Forest and Kondang Bandung Beach, and supplemented our dataset with 38 previously collected COI sequences of common mudskippers from three different populations from the southern coast of Java (Pasir Mendit Beach, Bogowonto Lagoon, and Baros Beach).
resultsThe study revealed that 47 common mudskippers from five different populations are separated into three genetically distinct clades (A, B, and C). These clades display genetic divergences ranging from 0.97% to 1.91%. Each clade exhibits high levels of haplotype diversity but relatively low nucleotide diversity, suggesting a previous bottleneck in population followed by a fast expansion. However, the phylogeny, haplotype network, and principal coordinate analysis indicate overlapping populations with no geographic separation within these clades. This suggests the potential occurrence of gene flow among these populations, which might have been facilitated by past geological events.
conclusionsThese results enhance our understanding of common mudskipper biodiversity in Indonesia. Further studies involving common mudskipper populations from various geographical sites in Indonesia are required to further enrich our understanding of the variation and evolution of this species.
