1 · What the graph read from it

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.

2 · The registry

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

backgroundDiabetes or high blood sugar (D/HBS) is a major global public health challenge, with a particularly high burden among middle-aged and older adults in China. While traditional risk factors (e.g., obesity, sedentary behavior) are well-studied, the impacts of environmental factors such as nighttime light (NL), air pollution, and the normalized difference vegetation index (NDVI) on D/HBS remain underexplored.

methodsUsing data from the China Health and Retirement Longitudinal Study (CHARLS, 2011-2015), we included 11,865 participants aged ≥ 45 years without baseline D/HBS. Cox proportional hazards models were employed to evaluate the independent effects of NL, air pollutants (PM

resultsThe median follow-up duration was 4.0 years. Among the 11,865 baseline participants, 371 developed incident D/HBS. NL was significantly associated with increased D/HBS risk (per IQR increase: HR = 1.15, 95% CI: 1.06-1.26). High exposure to PM

conclusionsNL and air pollution are independent risk factors for D/HBS, with synergistic effects exacerbating disease risk. NDVI confers protection by reducing pollutant exposure. Comprehensive strategies targeting light pollution control, air quality improvement, and optimized green space planning are imperative. Future studies should integrate individualized exposure assessments and elucidate causal environmental-metabolic pathways.
