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

backgroundAlport syndrome (AS) is one of the most common monogenic kidney disorders. Recent studies have highlighted the modifier effect of variants involving podocyte and non-collagenous extracellular matrix (ECM) proteins in AS.

methodsWe report a case series of eight patients with genetically proven AS and simultaneous variants involving podocyte and non-collagenous ECM proteins. Our aim is to describe the influence of such variants on the phenotype of patients with AS.

resultsWe identified 10 different type IV collagen variants. Patients were diagnosed with autosomal dominant (3/8), autosomal recessive (2/8), digenic (2/8) and X-linked AS (1/8). There were eight different variants involving podocyte and non-collagenous ECM proteins. The genes involved were CRB2, LAMA5, LAMB2, NUP107, MYO1E and PLCE1. Four patients (LAMB2, LAMA5 and PLCE1 variants) presented with nephrotic syndrome or nephrotic range proteinuria. Two patients had hearing loss. Most patients (7/8) had a family history of kidney disease. Two patients (LAMB2 and LAMA5 variants) were diagnosed with focal segmental glomerulosclerosis. Two patients developed end-stage kidney disease (LAMA5, MYO1E and NUP107 variants).

conclusionsAlthough mutations of podocyte and ECM proteins do not have phenotypic expression in monoallelic form, the presence of such variants could explain the phenotypic variability of AS.
