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

backgroundAntiplatelet agents have been widely used in the management of immunoglobulin A (IgA) nephropathy in the Japanese population. To systematically evaluate the effects of antiplatelet agents for IgA nephropathy, we conducted a meta-analysis of the published studies.

methodsData sources consisted of MEDLINE, EMBASE, the Cochrane Library, Ityu-shi (Japanese medical database), and bibliographies from the studies. The quality of the studies was evaluated from the intention to treat analysis and allocation concealment, as well as by the Jadad method. Meta-analyses were performed on the outcomes of proteinuria and renal function.

resultsSeven articles met the predetermined inclusion criteria. The use of antiplatelet agents showed statistically significant effects on proteinuria and renal function. The pooled risk ratio for proteinuria was 0.61 (95% confidence intervals (CI) 0.39-0.94) and for renal function it was 0.74 (95% CI 0.63-0.87).

conclusionsAntiplatelet agents resulted in reduced proteinuria and protected renal function in patients with IgA nephropathy. However, studies of high-quality design were rare, and most studies assessed surrogate outcomes. More properly designed studies are needed to reach a definitive assessment of this matter.
