The destruction of Gaza: Satellite measurements of the economic cost of war.
Article in PNAS nexus, 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
We map and estimate the economic impact of the Israel-Hamas war on the Gaza Strip that began after the 2023 October 7 attacks by Palestinian militant groups. We measure the extent of likely damage to Gaza's built environment derived from satellite radar time series data and estimate the impact caused by the conflict on Gazan economic activity via night-time luminosity measurements. After the first year of war, we find that 82% of each square kilometer of the Gaza Strip had been damaged at least once and that 67.9% of its built-up area has been destroyed. We estimate an average loss of night-time luminosity due to the conflict of 68.5%, and find that the 2023 November ceasefire coincided with a small but significant increase in luminosity. We translate our night-time luminosity losses into economic indicators: our results show that more than three quarters of Gaza's economy has been destroyed since the start of the conflict, and we estimate a loss of 2.6 billion USD of household expenditures caused by the damage. Our work establishes a novel framework for estimating the economic impact caused by conflicts with low latency, detailed spatial resolution and which is agnostic with respect to field data sourced from political actors.
