Investigation of nitrate and nitrite in commercially available infant formulas and baby foods in Iran and estimation of human health risks.

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
Levels of harmful nitrogen-containing substances have increased in many foods and drinks around the world. The impacts of dietary nitrate and nitrite on human health have been controversial topics for many years. The present study aimed to quantify the levels of nitrate and nitrite in infant formulas and baby foods sold in Iran and to estimate non-carcinogenic human health risk from exposure to these substances. The samples were gathered randomly and subsequently analyzed to detect nitrate and nitrite via Spectrophotometry. The ranges of nitrate and nitrite in the infant formulas were 0.221-1.347 (mean 0.645) mg/kg and 0.045-0.263 (mean 0.151) mg/kg, respectively. For baby foods, the ranges of nitrate and nitrite were 0.24-1.93 (mean 0.99) mg/kg and 0.04- 1.45 (0.36) mg/kg. Estimated Daily Intake (EDI) values of nitrate and nitrite in all the samples were below the acceptable daily intake (nitrate ADI = 3.7 mg/kg bw/day and nitrite ADI = 0.07 mg/kg bw/day established by FAO/WHO), showing that levels of these contaminants in infant formulas and baby foods may not cause toxicity in the infant and baby population. None of the infant formulas and baby foods in this study showed evidences of a non-cancer risk to the consumers. However, it is suggested that levels of nitrate and nitrite in these products and their related health risks be constantly monitored to prevent significant health hazards in the future.
