Complement Profiling in Glomerular Disease: Insights from Laser Microdissection and Mass Spectrometry.
Review in Clinical journal of the American Society of Nephrology : CJASN, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Complement activation occurs in most glomerular diseases. Complement activation on the kidney biopsy is evidenced by deposition of C3c and C1q on the kidney biopsy. The kidney biopsy provides only limited information as other complement proteins and complement-regulating proteins are not typically studied. Furthermore, kidney biopsy does not distinguish between activated versus inactive complement proteins. Laser microdissection and mass spectrometry (LMD/MS) is a relatively new methodology that can provide an in-depth evaluation of the proteomic profile of complement proteins, complement regulating proteins, complement pathways, and can also determine whether active complement fragments are present in the kidney biopsy sample. A semiquantitative burden of complement can be determined. Furthermore, proteins of a disease can be analyzed using principal component analysis, volcano plots, and heatmaps. In this review, the complement proteomic profile of diseases representing the spectrum of glomerular diseases are shown. The proteomic complement profile of membranous nephropathy associated with various antigens, Ig-associated GN, such as proliferative GN with monoclonal Ig deposits and fibrillary GN, C3 glomerulopathy, and IgA nephropathy, are shown. The findings show important differences in the complement profile including pathways of complement in each disease, and even within the disease, such as altered complement burden and profile between different antigens associated with membranous nephropathy. In conclusion, LMD/MS is a valuable tool for determining the complement proteins, complement-regulating proteins, complement pathways, and determining the burden of complement in each individual case of glomerular disease. In the era of new anticomplement drugs, it will become essential to accurately determine the complement profile in each kidney biopsy for a personalized approach to treating the glomerular disease. LMD/MS is a methodology that can help provide such answers.
