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

The ichthyofauna of the Ecuadorian portion of the Marañón drainage remains poorly documented, particularly in the tributaries of the Tigre River. Here, we provide the first consolidated dataset of freshwater fish species from the Conambo River, including voucher-based records, locality information, habitat and hydrological context, fisheries practices, and photographic documentation. The dataset comprises 118 species representing seven orders and 31 families, including taxa not previously recorded for Ecuador and specimens that may represent undescribed species. A complementary dataset documents fish species captured by Shiwiar and Sapara fishers, providing additional information on locally important taxa and subsistence practices. Together, these datasets offer a new baseline for taxonomic, biogeographic, and ecological research in one of the least studied regions of the Ecuadorian Amazon and support future efforts to document and understand freshwater biodiversity in the Marañón drainage.
