Cancer in glass workers: a systematic review and meta-analysis.
Synthesis in International archives of occupational and environmental health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeDue to a potential exposure to several definite or probable carcinogens, the IARC classified manufacturing of art glass, glass containers, and pressed ware as probably carcinogenic to humans in 1993 (Group 2A). Purpose of this study was to update the evidence from recently published scientific reports.
methodsWe searched for peer-reviewed articles published between 1993 and 2018 and combined result in terms of a meta-analysis. Overall, we considered twelve articles for a meta-analytic approach published after 1992.
resultsFrom a meta-analysis we derived a standardized incidence ratio (mSIR) and a standardized mortality ratio (mSMR) for lung cancer in men of 1.25 (95% CI 0.97-1.59) and 1.41 (95% CI 1.11-1.77), respectively. The estimated odds ratio (mOR) from five case-control studies was 1.25 (95% CI 0.90-1.73). Associated with an employment in glass factories, the estimated mSMR for larynx cancer was 2.38 (95% CI 1.23-4.16) based on two cohort studies; the mOR from four case-control studies was 1.35 (95% CI 0.73-2.52). Reports on elevated cancer risks at other sites were not consistent.
conclusionsOnly few studies assessed cancer risk solely in glass workers. Gained evidence from more recent reports supports the IARC rating from 1993. Our combined results add limited evidence to a moderately elevated risk for cancer of the airways.
