Assessing river discharge dynamics through relative surface water extent changes in river basins.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Surface water in rivers is vital for human society. However, our current understanding of the dynamics and drivers of river flows relies predominantly on stream gauging data, which are limited in spatial coverage and involve significant costs. Remote sensing techniques have emerged as complementary tools for monitoring river discharge, but these satellite-based methods often require complex data processing. This paper introduces a simple, yet effective and robust methodology to understand river discharge, using Australian rivers as a case study. Our findings reveal that changes in relative surface water extent within river basins can effectively capture river discharge dynamics. Moreover, we observe a linear relationship between relative surface water extent and river discharge in hilly basins and a quadratic relationship in flat basins. The new approach helps monitor river flows in ungauged river basins, and it has the potential to bridge the gap between local and regional understandings of water dynamics.
