Is mesangial hypercellularity with glomerular immaturity a variant of glomerulosclerosis?

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.
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
Our aim was to correlate an immunohistochemical pattern of selected podocyte cytoskeleton-associated proteins in children diagnosed with focal segmental glomerulosclerosis (FSGS) and diffuse mesangial proliferation accompanied by glomerular immaturity (Im-DMP) with the clinical courses of both diseases. The material included 33 renal biopsies obtained from children diagnosed with DMP with or without signs of glomerular immaturity (ten and 15 participants, respectively) or FSGS (eight patients). Ezrin, podocalyxin, synaptopodin and nephrin expression was evaluated by immunohistochemical assay. A positive reaction for ezrin, podocalyxin, synaptopodin and nephrin was observed in the most superficial, continuous 'layer' of podocytes in Im-DMP patients. This distribution closely mimicked the immunohistochemical pattern observed in FSGS. The severe initial course of Im-DMP was transient. Resistance to steroids (six children) and renal insufficiency (two patients) in these subjects subsided, whilst, in the FSGS patients, the resistance to steroids recognized in all the children and the renal insufficiency diagnosed in three of them were still present. Mimicry between the immunohistochemical pattern of glomerular immaturity in DMP and focal segmental glomerulosclerosis might explain the severe initial course of this nephrotic syndrome in children. The transient clinical character of the former may also indicate that it is not a variant of FSGS.
