Work-related airways disease and risk factors in Mozambiquan wood processing workers.

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
backgroundInhalation of wood dust particulates, bioaerosols and chemical components cause airway disease of a sensitising or irritative nature.
aimsThis study investigated the disease burden and factors associated with work-related airways disease among wood processors.
methodsA cross-sectional study enrolled 450 workers from 21 Mozambican wood mill and furniture industries. Work-related asthma (WAS) and work-related ocular-nasal (WONS) symptoms were evaluated, using European Community Respiratory Health Survey (ECRHS) questionnaire. Objective assessments included spirometry, fractional exhaled nitric oxide (FeNO) and Phadiatop tests.
resultsThe average age was 38 years, three-quarters did not smoke and almost half were atopic. The proportion of workers with WAS was 14% and WONS was 40%. There were 3% that demonstrated bronchial reversibility, 16% fixed airway obstruction and 5% with FeNO > 50 ppb. WONS was positively correlated with female sex [odds ratio (OR) = 2.60, 95% confidence interval (CI) 1.15-5.90] and atopy (OR = 2.04, 95% CI 1.20-3.47). Bronchial reversibility was associated with increasing age (OR = 1.06, 95% CI 1.02-1.10), atopy correlated with high FeNO (OR = 2.85, 95% CI 1.09-7.44). Processing Mutondo wood was positively correlated with WAS (ORadj = 3.68, 95% CI 1.58-8.58), and WONS (ORadj = 9.34, 95% CI 4.54-19.20). Certain wood types, Missanda (ORadj = 6.84, 95% CI 4.17-11.20), Panga-panga (ORadj = 2.31 95% CI 1.49-3.60) and Mahogany bean (ORadj = 2.52, 95% CI 1.41-4.51) were primarily correlated with WONS.
conclusionsMozambiquan wood processors experience significant work-related airway disease attributable to dust particulate. Mutondo wood type, was positively correlated with both lower and upper airway symptoms, whereas other species were linked only to upper airway symptoms.
