An empirical investigation of environmental impacts of agglomeration economies in major cities of Pakistan.
Article in Scientific reports, 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
Agglomeration economies arise when firms and people co-locate in cities. These economies are determined by city's activity, size, land and labor prices, and affect the overall environmental conditions of cities in developing economies. The present study empirically investigates environmental impacts of agglomeration economies in major cities of Pakistan during 2002-2019, using Dynamic Fixed Effects (DFE), Pooled Mean Group (PMG), and Mean Group (MG). The findings of the MG model reveal that over the time, the physical environment is negatively affected by agglomeration economies; e.g. population increase (-1.89, p < 0.05), increase in number of factories (-7.11, p < 0.001), increased number of registered vehicles (-1.02, p < 0.05), by creating pressures on human health, civic amenities, and air quality of cities. The study suggests decentralization of big cities, and reshaping of medium and small cities to control population pressure and industrial pollution in major cities of Pakistan.
