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
objectivesSpecial chemistry parameters are useful in the diagnosis and management of inherited disorders, liver disease, and immunopathology. Evidence-based pediatric reference intervals (RIs) are required for appropriate clinical decision-making and need to be verified as new assays are developed. This study aimed to evaluate the applicability of pediatric RIs established for biochemical markers on the ARCHITECT for use on newer Alinity assays.
methodsAn initial method validation was completed for 16 assays, including precision, linearity, and method comparison. Sera collected from approximately 100 healthy children and adolescents as part of the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER) were also analyzed on the Alinity c system. Percentage of results within established ARCHITECT RIs were calculated and considered verified if ≥90 % fell within established limits. New RIs were established for three electrolytes, glucose, and lactate wherein no data were previously reported.
resultsOf the 11 assays for which CALIPER pediatric RIs were previously established on ARCHITECT assays, 10 met the verification criteria. Alpha-1-antitrypsin did not meet verification criterion and a new RI was established. For the other 5 assays,
conclusionsHerein, pediatric RIs were verified or established for 16 chemistry markers in the CALIPER cohort on Alinity assays. Findings support excellent concordance between ARCHITECT and Alinity assays with one exception (alpha-1-antitrypsin) as well as robustness of age- and sex-specific patterns originally reported by CALIPER in healthy Canadian children and adolescents.
