Do we need flexible machine-learning algorithms to assess the effect of long-term exposure to fine particulate matter on mortality?: An example from a Canadian national cohort.
Article in Environmental epidemiology (Philadelphia, Pa.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Evidence suggests the existence of nonlinearity in the relationship between long-term fine particulate matter (PM Methods: Using a cohort of the Canadian Community Health Survey respondents (followed from 2005 until 2014), we obtained consented respondents' baseline characteristics, time-varying annual average PM Results: Among 62,365 participants, the 10-year cumulative mortality rate differences per 1000 participants were -0.23 (95% confidence intervals: -0.46, 0.00), -0.83 (-1.24, -0.43), and -0.67 (-1.27, -0.06) for parametric g-computation, targeted minimum loss-based estimator using parametric models, and targeted minimum loss-based estimator with SuperLearner and six candidate algorithms of high flexibility, respectively. Changing the hyperparameters did not meaningful change estimates or algorithm weights. Conclusions: All three methods of reducing long-term exposure to PM
