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

Muscle biopsy is required to provide a definitive diagnosis in many neuromuscular disorders. It can be performed through an open or needle technique under local anesthesia. The major limitations of the needle biopsy technique are the sample size, which is smaller than that obtained with open biopsy, and the impossibility of direct visualization of the sampling site. However, needle biopsy is a less invasive procedure than open biopsy and is particularly indicated for diagnosis of neuromuscular disease in infancy and childhood. The biopsied muscle should be one affected by the disease but not be too weak or too atrophic. Usually, in case of proximal muscle involvement, the quadriceps and the biceps are biopsied, while under suspicion of mitochondrial disorder, the deltoid is preferred. The samples must be immediately frozen or fixed after excision to prevent loss of enzymatic reactivity, DNA depletion or RNA degradation. A battery of stainings is performed on muscle sections from every frozen muscle biopsy arriving in the pathology laboratory. Histological, histochemical, and histoenzymatic stainings are performed to evaluate fiber atrophy, morphological, and structural changes and metabolic disorders. Moreover, immunohistochemistry and Western blotting analysis may be used for expression analysis of muscle proteins to obtain a specific diagnosis. There are myopathies that do not need muscle biopsy since a genetic test performed on a blood sample is enough for definitive diagnosis. Muscle biopsy is a useful technique which can make an enormous contribution in the field of neuromuscular disorders but should be considered and interpreted together with the patient's family and clinical history.
