Impact of World Trade Center dust exposure on upper-aero digestive tract disorders and sinonasal surgery: findings from patients seen in the Department of Otolaryngology - Head and Neck Surgery at Mount Sinai Hospital.
Article in Occupational and environmental medicine, 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
objectiveWe assessed upper-aero digestive tract disorders in World Trade Center (WTC) patients seen in the Otolaryngology - Head and Neck Surgery Department of a large New York City hospital system and the association between WTC exposure and sinonasal surgery for chronic rhinosinusitis (CRS).
methodsRetrospective review of medical records of all WTC patients seen between July 2002 and December 2023. Primary exposure was measured by arrival date and exposure length to the disaster site. Primary outcomes were upper-aero digestive tract disorders and sinonasal surgery.
results3118 WTC patients were reviewed. Of these, 1162 (37.3%) had CRS. CRS patients were more likely female (p=0.03) and had higher proportion of comorbid obstructive sleep apnoea (OSA) (p<0.0001), allergic rhinitis (p<0.0001) and gastro-oesophageal reflux disease (p<0.0001). 355 (31.0%) CRS patients underwent sinonasal surgery. Relative to the medically managed patients, surgical CRS patients were younger at time of 9/11 (p=0.006), had a higher proportion of comorbid OSA (p=0.02) and earlier exposure (arrival date 11 September-13 September prior to rainfall) (p=0.001). CRS patients with early exposure demonstrated significantly greater odds of undergoing sinonasal surgery compared with those with late exposure (adjusted OR 1.61; 95% CI 1.2 to 2.3).
conclusionsEarlier arrival at WTC site increased the risk of needing surgery for responders with CRS. Higher levels of irritant exposure prior to rainfall on 14 September 2001 may have caused significant epithelial injury to the sinonasal mucosa of WTC patients, leading to an elevated prevalence of CRS requiring surgical intervention.
