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

objectivesTo investigate the incidence, genetic mutation characteristics, and prognosis of fatty acid oxidation disorder (FAOD) in neonates in Qingdao.

methodsClinical data of neonates diagnosed with FAOD from 2014 to 2023 at the Qingdao Neonatal Disease Screening Center were collected and analyzed to determine the incidence, genotype, and prognosis.

resultsAmong 562 225 neonates screened, 42 were diagnosed with FAOD across six types, yielding an overall incidence of 1/13 386. Primary carnitine deficiency was the most common (20 cases, 48%), with one case showing growth retardation during follow-up. Medium-chain acyl-CoA dehydrogenase deficiency was identified in 6 cases, all of whom demonstrated normal development during follow-up. Short-chain acyl-CoA dehydrogenase deficiency was diagnosed in 5 cases, with one case exhibiting skin erythema, papules, scaling, and dryness during follow-up. Very-long-chain acyl-CoA dehydrogenase deficiency was diagnosed in 5 cases; during follow-up, one patient died and another experienced recurrent rhabdomyolysis. Short/branched-chain acyl-CoA dehydrogenase deficiency was found in 4 cases, with one case showing language regression during follow-up. Multiple acyl-CoA dehydrogenase deficiency was detected in 2 cases; during follow-up, one patient died and one exhibited delayed motor development. Genetic testing performed on 37 of the 42 patients with FAOD identified a hotspot mutation, c.1400C>G, in the

conclusionsIn Qingdao, primary carnitine deficiency is the most prevalent subtypes of FAOD in neonates, characterized by the hotspot mutation c.1400C>G in the
