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

purposeMucolipidosis (ML) II, MLIII alpha/beta, and MLIII gamma are rare autosomal recessive lysosomal storage disorders. Data on the natural course of the diseases are scarce. These data are important for counseling, therapies development, and improvement of outcome. The aim of this study is to gain knowledge on the natural history of ML by obtaining data on survival, symptom onset, presenting symptoms, diagnosis, and pathogenic variants associated with the MLII or MLIII phenotype.

methodsA systematic review on all published MLII and MLIII cases between 1968 and August 2019 was performed.

resultsThree hundred one articles provided data on 843 patients. Median age at diagnosis: 0.7 for MLII and 9.0 years for MLIII. Median survival: 5.0 for MLII and 62.0 years for MLIIIII. Median age of death: 1.8 for MLII and 33.0 years for MLIII. Most frequent causes of death in all ML were pulmonary and/or cardiac complications. Pathogenic variants were described in 388 patients (GNPTAB: 571, GNPTG 179).

conclusionThis review provides unique insights into the natural history of MLII and MLIII, with a clear genotype-phenotype correlation with the most frequent pathogenic variant c.3503_3504del in MLII and in MLIII alpha/beta c.22A>G for GNPTAB. All pathogenic GNPTG variants resulted in MLIII gamma.
