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
This study sought to validate the external calibration curve (CAL) method for iodine analysis in 26 selected foods and then to compare the test result with the isotope dilution mass spectrometry (IDMS). Iodine was extracted by tetramethylammonium hydroxide (TMAH) and determined by ICP-MS using CAL and IDMS methods. The results showed that iodine determination using the IDMS method had higher precision than the CAL method (LOD of the method were 0.01 and 0.02 mg/kg, respectively). However, both methods showed good accuracy and precision for all SRM and the 26 food samples. Test results from both methods had a strong correlation (R
