Health risk assessment via Monte Carlo simulation and sensitivity analysis for fluoride and nitrate content in bottled waters consumed in Kermanshah city, Iran.
Article in Scientific reports, 2025. 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
Bottled water consumption has increased in recent decade due to many reasons, especially significant decline in water quality and quantity. The concentration of fluoride and nitrate in bottled waters may vary based on brands and locations. This study was carried out to determine the levels of fluoride and nitrate in bottled waters consumed in Kermanshah city and assess the related non -carcinogenic risks. Totally, 22 brands of bottled water were collected from markets. Fluoride and nitrate measurement was conducted via a UV-visible spectrophotometer (DR-5000). From the results, Fluoride and nitrate levels in the studied bottled waters were 0.32 ± 0.18 mg/L and 2.3 ± 1.41 mg/L, respectively. The risk of non-carcinogenic in term of HQ for fluoride exposure, for only 2 brands of bottled water were > 1 for infants group. HQ was less than 1 for nitrate in all the brands for all the age groups revealed non-carcinogen risks. Hazard index (HI) calculation showed that only in 2 brands of bottled water HI was > 1 for infants group. The HI were as infants (0.64) > children (0.36) > teenagers (0.27) > adults (0.24). From Monte Carlo simulation, 95th Percentile for nitrate and fluoride was less than 1 for all the groups. This result indicated non-carcinogenic risks of nitrate and fluoride for 95% of the studied groups. Moreover, sensitivity analysis showered that concentration for both nitrate and fluoride had the highest effect on HQ for all the groups. From this work, although fluoride and nitrate content in the bottled waters were at standard range, but infants were proportionally at higher risk.
