Building-integrated solar water disinfection system for reliable year-round drinking water safety.
Article in NPJ clean water, 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
Waterborne pathogens pose a major threat to global water safety. Solar energy could provide a critical opportunity for households without reliable access to safe water; however, many solar-driven household water treatment systems (HWTS) fail to provide adequate year-round quantities of clean drinking water, as they often cannot remove viruses during low-sun periods, exposing users to waterborne diseases. We demonstrate the disinfection capacity of a novel concentrating solar water-energy management system for building envelopes that integrates on-site water collection with phyto-derived photosensitization, solar water disinfection (SODIS), and solar pasteurization (SOPAS) within a roofing system suitable for a range of housing types. By combining outdoor testing in field settings with computational modeling, we demonstrate the water treatment capacity as a function of the year-round variations in solar resources available in different climates: Cape Town, South Africa; Sololá, Guatemala; and Phoenix, AZ, USA. Modeled annual performance across each site indicates that the approach could treat more than 70 L/m
