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

purposeThe impacts of body mass index (BMI) on the prognosis of primary IgA nephropathy (IgAN) remain controversial. This systematic review and meta-analysis aimed to solve these issues.

methodsWe searched the PubMed, EMBASE, and Cochrane Library to screen articles investigating the BMI and primary IgAN. BMI was classified according to the World Health Organization as high (≥ 25.0 kg/m

resultsSix studies with a total of 1723 patients were included in this study. High BMI was demonstrated to be associated with increased baseline levels of serum creatinine (weighted mean difference (WMD) 9.54, 95% confidence interval (CI) 0.63-18.45), blood uric acid (WMD 19.85, 95% CI 10.11-29.59) and urine protein (WMD 0.37, 95% CI 0.21-0.53). Patients with high BMI also showed compromised eGFR at diagnosis (WMD - 8.39, 95% CI - 11.62 to - 5.16) with a higher incidence rate of hypertension (odds ratios (OR) 2.59, 95% CI 1.44-4.66) and higher global optical scores (WMD 1.22, 95% CI 0.70-1.74). Regarding the prognosis, high BMI was significantly associated with the incidence of adverse renal outcomes (OR 2.43, 95% CI 1.66-3.55, P < 0.001) and deteriorated eGFR at the last follow-up (WMD - 11.10, 95% CI - 16.96 to - 5.25, P < 0.001), with non-significantly poorer renal disease-free survival (hazard ratio 1.79, 95% CI 0.58-5.50, P = 0.31).

conclusionHigh BMI was associated with severe onset and poor prognosis of primary IgAN. The management of BMI could be a novel method to promote the therapeutic outcomes of primary IgAN.
