Experimentally recreated workplace environments contain submicron crystalline silica particles, including ultrafine particles, which have been identified in the mediastinal lymph nodes of construction 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
objectivesAlthough ultrafine particles are suspected to contribute significantly to occupational exposure to crystalline silica, they have not yet been definitively identified in workplaces or human tissues.
methodsParticles were generated in three 60-minute tests in a glove box: cutting kerb or granite pavement, drilling solid cinder block. The particle concentrations per cm
resultsThe particle concentration was high when cutting kerb or granite pavement (10 000-20 000 cm
conclusionUltrafine silica particles are produced in conditions that mimic typical construction work processes, but the quantity produced varies according to the task. Similar characteristics were observed in ultrafine silica particles in both MLN samples and experimental aerosols.
