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

introductionThe prevalence rates of the common histopathologic subtypes of childhood nephrotic syndrome associated with steroid resistance appear to be changing globally. In Sub Saharan Africa (SSA), the trend is similar over the past few decades.

aimThis systematic review aims to determine the current prevalence rates of the histopathologic subtypes associated with childhood steroid-resistant nephrotic syndrome (SRNS) in SSA.

methodsA search of the PubMed, Google and African Journals Online databases was conducted from January to December 2018 using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flow-chart to identify relevant articles which met the aim of the systematic review. A qualitative synthesis and descriptive analysis of the extracted data were then conducted. The mean values for the prevalence rates of the reported histopathologic subtypes were calculated. A meta-analysis was not done due to few numbers of studies reviewed. The review is registered with PROSPERO, number CRD42018111916.

resultsIn the West African sub-region, the currently reported histopathologic subtypes associated with childhood nephrotic syndrome are focal segmental glomerulosclerosis (FSGS), minimal-change nephropathy (MCN), membrano-proliferative glomerulonephritis (MPGN), membranous nephropathy (MN) and mesangial proliferative glomerulonephritis (MesPGN). The picture is the same in South Africa. More importantly, the predominant histopathologic lesions associated with steroid resistance are FSGS (West Africa) and MCN/FSGS (South Africa), with mean prevalence rates of 57.2% and 36.1% respectively.

conclusionThe prevalence of FSGS is currently high in childhood nephrotic syndrome in SSA. This histopathologic subtype remains the commonest lesion associated with SRNS in this part of the globe.
