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

backgroundPremature neonates need adequate nutritional support to provide sufficient essential nutrients for optimal growth. Calcium (Ca) is one of the important nutrients in parental nutrition support of premature infants. This study aimed to compare the effect of continuous and intermittent bolus infusion of Ca on the incidence of metabolic bone disease (MBD) in preterm infants.

methodsThis randomized double-blind clinical trial was conducted on ninety preterm infants in the NICU of Al-Zahra Hospital in Tabriz, Iran. The preterm infants were randomly allocated to either a continuous infusion group (received 4-5 ml/kg/day of Ca gluconate 10% by PN solution in a 24-h period) or an intermittent bolus administration group (received 1-2 ml/kg/day Ca gluconate 10% three to four times per day). Serial serum levels of Ca, phosphorous, alkaline phosphatase (ALP), vitamin D and parathyroid hormone (PTH) were assessed on the 7th day, 30th day and 45th day of life.

resultsA total of 78 infants completed the study. The serum ALP level on the 45th day after birth was 753.28 ± 304.59 IU/L and 988.2 ± 341.3 IU/L in the continuous infusion and intermittent bolus administration groups, respectively (P < 0.05). MBD in preterm infants with ALP levels above 900 IU/L on the 45th day of life was significantly lower in the continuous infusion group than in the intermittent bolus administration group (p < 0.05). The mean serum levels of calcium, phosphorus, vitamin D and PTH in 45-day-old infants were not significantly different between the two groups.

conclusionThe MBD in preterm infants who received continuous infusion of Ca was lower than that in preterm infants who received intermittent bolus administration of Ca.
