Redescription of Parambassis macrolepis (Bleeker, 1856), a senior synonym of Parambassis piratica (Roberts, 1989), with descriptions of three new species of Parambassis (Ovalentaria: Ambassidae) from Sumatra and Borneo.

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
Parambassis macrolepis (Bleeker, 1856), a poorly characterized species of glass perchlet (Ovalentaria, Ambassidae), is redescribed and Parambassis piratica (Roberts, 1989) is regarded as its junior synonym. Based on integrative taxonomy, three new species of Parambassis, previously misidentified as P. macrolepis, are newly described herein as Parambassis kapuasensis sp. nov., Parambassis seruyanensis sp. nov. and Parambassis sumatrana sp. nov., from West Kalimantan, Central Kalimantan and Sumatra, respectively. These species can be distinguished from each other by a series of morphological differences, including differences in head characteristics and the number of scales along the lateral line. A phylogenetic analysis based on the 'barcode' fragment of the mitochondrial cytochrome c subunit I (COI) gene showed that each species forms a monophyletic group, diverging to others by more than 3% uncorrected genetic distances. Furthermore, COI-based automatic species delimitation methods retrieved the same species-level taxonomic units, confirming the validity of all new species of Parambassis described in this work.
