1 · What the graph read from it

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.

2 · The registry

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

objectiveThe automated reticulocyte parameters (absolute reticulocyte count, immature reticulocyte fraction (IRF) and reticulocyte hemoglobin content (RET-He)) are of value in managing adults and older children with a variety of hematological disorders. However, the lack of reference intervals for these parameters in neonates and young infants has limited their application to that population. STUDY

designDuring a span of 12 months (29 May 2014 to 5 May 2015), a convenience sample of reticulocyte parameters were run from clinically ordered complete blood counts (CBCs) of infants within the first 90 days after birth. Measuring the reticulocyte parameters as a research-only adjunct to the CBC did not require any additional blood or generate a patient charge, and the reticulocyte results were not reported to the provided and did not appear in the clinical records. Values from neonates who had a transfusion or a diagnosis of anemia were subsequently excluded from the reference data set.

resultsNine Intermountain Healthcare clinical laboratories contributed 8438 CBCs to the initial reticulocyte parameter database. From these, 1806 were excluded because of a transfusion or a diagnosis of anemia, leaving 6632 in the reference interval database. The parameters charted over the first 90 days after birth were: (1) blood hemoglobin concentration (g dl(-1)), (2) mean corpuscular volume (fL), (3) reticulocyte count (x10(3) per μl), (4) IRF (%) and (5) RET-He (pg).

conclusionsThe new reference interval charts can help clinicians identify abnormalities in the reticulocyte parameters. This information could be of value in identifying and following neonates with various hematological problems including hemolytic disorders, occult hemorrhage, or iron deficiency or other limitations of erythrocyte production.
