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

backgroundPhenylketonuria (PKU) is a rare autosomal recessive disorder caused by mutations in the gene encoding phenylalanine hydroxylase, an enzyme that converts phenylalanine to tyrosine. Untreated, PKU is characterized by a range of neuropsychological and neurocognitive impairments. Due to ubiquitous newborn genetic screening programs, treatment for PKU can be commenced shortly after birth and can prevent many of the severe manifestations of the disease. However, lifelong management is critical for patients with PKU as high levels of phenylalanine are neurotoxic. As for all chronic diseases, long-term management can be challenging and most adult patients with PKU become lost to follow-up (LTFU). A survey of PKU clinics across the United States and a multidisciplinary Expert Meeting were conducted to develop best practices to engage LTFU patients with PKU.

resultsWe defined LTFU patients with PKU as "patients with no contact with the clinic for at least 2 consecutive years." Combining the results from our survey and our discussion at the Expert Meeting, we have prepared six best practice recommendations to engage LTFU patients with PKU: 1) Ensure patients are aware of the current treatment guidelines for PKU; 2) Communicate to patients any new treatment and diet options as they become available for PKU; 3) Consider the neuropsychological and neurocognitive aspects of PKU; 4) Prioritize motivated LTFU patients; 5) Explore new approaches of outreach to LTFU patients; and 6) Formalize approaches to track and/or identify PKU patients.

conclusionWe strongly advocate the importance of engaging LTFU patients with PKU and encourage implementation of our best practice recommendations. Although it takes time and effort to engage LTFU patients, we believe that clinics are capable of supporting this significant patient group.
