Efficacy and safety of high and low dose recombinant human erythropoietin on neurodevelopment of premature infants: A meta-analysis.
Synthesis in Medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundTo evaluate the effect of recombinant human erythropoietin (rhEPO) in nervous system of premature infants including different dosage.
methodsThe multiple databases like Pubmed, Embase, Cochrane databases and China National Knowledge Database were used to search for the relevant studies, and full-text articles involved in the evaluation on effect of rhEPO for neurodevelopment among premature infants. Review Manager 5.2 was adopted to estimate the effects of the results among selected articles. Forest plots, sensitivity analysis and bias analysis for the articles included were also conducted.
resultsFinally, 10 eligible studies were eventually satisfied the included criteria. The results showed that rhEPO was much higher than placebo group in composite cognitive score (MD = 5.89, 95% confidential interval {CI} [1.95, 9.82], P = .003; I2 = 89%), there was no significant difference between rhEPO and placebo groups (RR = 0.93, 95% CI [0.60, 1.43], P = .74; I2 = 51%) and no difference in neurodevelopmental impairment between rhEPO and placebo was insignificant (RR = 0.55 95% CI [0.30, 1.02], P = .06). Composite cognitive score in high dose rhEPO was much higher than placebo group (MD = 10.39, 95% CI [8.84, 11.93], P < .0001, I2 = 0%) and low dose rhEPO also had higher composite cognitive score than placebo group (MD = 2.58, 95% CI [0.80, 4.37], P = .004, I2 = 11%). Limited publication bias was observed in this study.
conclusionRecombinant human erythropoietin might be a promotor for neurodevelopment among premature infants with limited adverse events.
