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 clinical characteristics, treatment strategies, and outcomes of very low birth weight (VLBW)/extremely low birth weight (ELBW) preterm infants in Weihai from January 2017 to December 2019.

methods107 VLBW/ELBW preterm infants admitted to our hospital were recruited as the study cohort and divided into three groups: the < 1000 g group (n = 11 cases), the ≥ 1000~1250 g group (n = 32 cases), and the ≥ 1250~1500 g group (n = 64 cases). The clinical characteristics of the VLBW/ELBW preterm infants in each group were analyzed, and the hospitalization duration times, the survival rates, the ventilator use, the main complications, and the follow-ups in each group were compared statistically.

resultsThere were significant differences in the occurrences of maternal anemia during pregnancy, the birth weights, the gestational ages, the births of singletons, twins, or multiples, the hospitalization duration times, the occurrences of late-onset sepsis (LOS), and the occurrences of periventricular intraventricular hemorrhages (PIVH) among the three groups (P < 0.05). Our multivariate logistic regression and ROC curve analyses showed that the lower the gestational age (OR = 12.56, 95% CI: 2.45~14.63, P = 0.01), the lower the birth weight (OR = 8.69, 95% CI: 1.95~10.34, P = 0.03), and the premature rupture of membranes (OR = 6.44, 95% CI: 1.03~9.77, P = 0.04) and LOS (OR = 9.64, 95% CI: 1.67~18.99, P = 0.02) would induce a higher death rate among premature infants. Furthermore, after one year of follow-up, the psychomotor development indexes (PDI) of the different birth weight groups were increased along with the birth weight, and the differences were statistically significant (χ

conclusionStrengthening perinatal health care and actively preventing and treating various complications are of great significance in improving the survival rate and long-term quality of life of VLBW/ELBW premature infants.
