1 · What the graph read from it

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.

2 · The registry

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

backgroundSilicosis is a progressive occupational lung disease caused by inhalation of respirable crystalline silica. Stone countertop workers are at risk of developing silicosis associated with engineered stone (ES) due to its high silica content and widespread use. This qualitative study assessed countertop workers' knowledge, attitudes, and practices regarding silica hazards.

methodsWe recruited 20 participants for semi-structured interviews through purposive sampling of workplaces in Los Angeles, California. Eligibility requirements: employment in countertop fabrication, exposure to engineered stone, ≥ 18 years old, and English or Spanish proficiency. Interviews were recorded, translated, and transcribed. Two researchers employed thematic and content analysis to code transcripts using both inductive and deductive methods.

resultsAll respondents were Latino men, 90% of whom were foreign-born, with a median age of 44 years and a median work tenure of 20 years. We identified five themes: (1) Hazardous work environments: Respondents regularly engaged in dry-cutting practices (68%), and half reported that their employers did not reliably provide respirators. (2) Insufficient training and educational resources: Respondents possessed basic knowledge that dust caused lung disease (90%); however, most acquired knowledge through word-of-mouth or media. (3) Employment vulnerability: Workers feared being fired for raising safety concerns. (4) Workforce entrapment: Although many workers considered leaving the industry, they were hindered by a lack of legal immigration status or alternative skills, as well as the presumed lower pay in a new industry. (5) Worker-identified solutions: Workers suggested wet cutting, workplace training, and regulation of ES, including its elimination.

conclusionThe results support continued policy, regulatory, and enforcement efforts aimed at minimizing silica exposure. Workers recommended workplace and upstream solutions, such as eliminating ES.
