Relationship between short-term exposure to ambient sulfur dioxide and length of hospital stay after surgery for osteoporotic fractures: a distributed lag non-linear analysis.
Observational study in BMC public health, 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
backgroundWhile long-term air pollution is a known risk factor for fracture, its short-term impact on prognosis, particularly length of stay (LOS) in hospital following surgery, remains unclear.
objectivesThis study aimed to assess the relationship between short-term exposure to ambient sulfur dioxide (SO
methodsA retrospective observational analysis of secondary hospital records from 3567 patients treated in Kunshan, China, between 2017 and 2024 was conducted. Individual clinical records were linked to daily area-level ambient SO₂ and meteorological data, and a distributed lag non-linear model was used to assess the association between short-term SO₂ exposure and LOS.
resultsA non-linear, J-shaped association was identified between SO
conclusionsShort-term ambient SO₂ exposure was associated with prolonged LOS after osteoporotic fracture surgery, particularly at higher levels of exposure. These findings highlight the potential relevance of ambient air pollution to postoperative outcomes in vulnerable patient populations.
