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

objectiveTo investigate the correlation between hypoglycemia and positive rate of inborn error of metabolism (IEM) in neonatal intensive care unit.

methods160 patients from a neonatal intensive care unit were enrolled. Blood glucose was measured by Roche Modular chemistry. The dry blood on filter papers, collected from 160 patients, was tested by tandem mass spectrometry to detect 35 inborn errors of metabolism. Clinical follow-up of all the patients was at least in an interval of 12 months. The mean observation period was 13.5 months per child.

findingsBased on the ROC curve, the optimal cut-off value of hypoglycemia as an indicator for screening for IEMs was projected to be 2.8 mmol/L, which yielded a sensitivity of 71.4% and a specificity of 76.5%. The patients were divided into two groups: hypoglycemia group (48 cases) and the control group (112 cases). 5(10.4%) of the 48 patients in the hypoglycemia group were positive, while only 2(1.8%) of the 112 patients in the control group were positive. The difference of the positive rate in the screening for IEMs between the two groups was significant (χ(2)=4.10, P<0.05); the relative risk (RR) was 5.83 (95% CI: 1.06-32.12).

conclusionThe risk of patients with hypoglycemia suffering from IEMs was significantly higher than that of the non-hypoglycemia patients in NICU, based on cut-off value of 2.8mmol/L.
