Present-day coastal subsidence and inundation risk to socioeconomic exposure in Chennai City, India.
Article in Scientific reports, 2026. 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
Chennai, a coastal megacity on India's southeastern coast, has experienced frequent coastal hazards, notably the 2004 tsunami and 2015 floods. Land subsidence along urban coastlines, a critical but often overlooked component of vertical land motion (VLM), exacerbates relative sea-level rise (RSLR) and intensifies flood hazards, undermining long-term coastal resilience. This study quantifies Chennai's coastal vulnerability by integrating high-resolution interferometric synthetic aperture radar (InSAR) observations from Sentinel-1 (2016-2024), tide gauge (1993-2023), and satellite altimetry (1993-2024) data with elevation, population, and infrastructure datasets. Results reveal InSAR-derived subsidence rates up to -15 mm/yr within 30 km of the coastline, combined with a sea-level rise of ~ 2.8 mm/yr. Projected inundation for 2030, 2050, and 2100 under IPCC SSP2-4.5, SSP3-7.0, and SSP5-8.5 scenarios incorporates RSLR, VLM, and 6 m storm surge effects. By 2100, inundation extent is expected to increase by 136.9 km
