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

backgroundRecently, a new classification has been established for membranoproliferative glomerulonephritis (MPGN). However, the effect of the new classification on MPGN treatment is not fully understood.

methodsWe conducted a retrospective study of 87 patients with biopsies diagnosed as MPGN. We reclassified 87 MPGN patients diagnosed between 1977 and 2014 at our hospital, according to the new classification, and analyzed both primary immune complex (IC)- and Alternative pathway (AP)-mediated MPGN [corrected] in terms of clinicopathological features, treatment, and renal prognosis.

resultsProteinuria was abundant in the IC-mediated MPGN group (p = 0.0063), and the serum albumin level was significantly lower in the IC-mediated MPGN group (p = 0.0186). The serum C3 value was significantly lower in the CP-mediated MPGN group (p = 0.0317). Serum CH50 values were also lower in the CP-mediated MPGN group (p = 0.0404). However, glomerular deposition of C3 showed no significant differences in immunofluorescence findings. The 148.6-month renal survival rate was similar in both groups (p = 0.445).

conclusionThese results suggested no significant differences in complement activation of the solid phase in local glomeruli and therefore equivalent in renal prognosis [corrected].
