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
The William Fine approach is among the limited number of methods, introducing a metric referred to as the J index and discussing safety costs to evaluate control measures. Therefore, this study aimed to update the "cost factor" in the William Fine method in proportion to the economic power in selected production industries in Iran. Based on the International Standard Industrial Classification (ISIC), three selected production industries were the automotive, pharmaceutical, and food industries. The Delphi technique was used to achieve the values of safety costs in economic sectors. Due to high exchange rate fluctuations and the possibility of using the cost invoice table over time and the producer price index, the correction factor was calculated. Furthermore, the fuzzy logic method determined the cost factor of William Fine's method. The gap between the minimum and maximum costs is significantly broader in the automotive industry compared to the pharmaceutical and food industries. The cost factor correction for the automotive industry stands at 1.144, while it is 1.222 for pharmaceuticals and 1.141 for the food industry. These figures are expected to be generalized in the coming years. The present study revealed that due to the impossibility of accurate access to data related to cost performance and safety investment in industries, the Delphi method could be acceptable to achieve the range of safety costs in industries. Updating this table has enabled selected industries to achieve more accurate control costs or risk aversion estimates.
