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

Background: Neurofibromatosis Type 1 (NF1) is a genetic disorder with a wide range of clinical manifestations, including skin changes, behavioral issues, and skeletal deformities. Despite being relatively common, there is a lack of local studies in the Philippines. Objective: This study aimed to investigate profiles of individuals with NF1 seen at the Philippine General Hospital and their outcomes following various interventions. Methods: A review of medical records of all patients with confirmed NF1, identified through databases from the Institute of Human Genetics and the Philippine General Hospital from 1999 to 2022, was done. Demographic, clinical, treatment, and outcome data were reviewed and evaluated. Data gathered included clinical profile, interventions, and survival. Additionally, for patients with congenital pseudarthrosis and NF1, radiologic findings, treatments, and functional outcomes such as union maintenance and refracture were evaluated. Results: The mean age of 50 patients with NF1 at initial evaluation was 10.8 ± 5.5 years, with an average symptom onset at 1.9 ± 3.7 years. Common features included café-au-lait spots (100%), axillary and inguinal freckling (17%), and cutaneous (15%) or plexiform (11%) neurofibromas. Interventions noted included surgery for intracranial tumors and multiple surgeries for congenital pseudarthrosis of the tibia. Six patients with congenital pseudarthrosis of the tibia had a median age of presentation at 0.5 years, with most requiring repeated surgical interventions and receiving bisphosphonate treatment for better bone union outcomes. Conclusion: A multidisciplinary approach is necessary to address the varied clinical manifestations of NF1, including biological, biomechanical, psychological, and developmental issues. Standardization and adherence to established multidisciplinary protocols are necessary to achieve optimal outcomes.
