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

backgroundThe relationship between time-averaged serum uric acid (TA-SUA) levels and prognosis in peritoneal dialysis (PD) patients are rarely discussed.

methodsThis was a retrospective cohort study. PD patients recruited from January 1, 2011, to December 31, 2020, were included. Baseline and follow-up uric acid levels over 1 year were collected to calculate time-averaged serum uric acid (TA-SUA) levels. Patients were divided into four groups based on TA-SUA quartiles: Q1 (<5.1 mg/dl), Q2 (5.1-5.8 mg/dl), Q3 (5.8-6.8 mg/dl), and Q4 (>6.8 mg/dl).

resultsA total 487 PD patients with a mean age of 52.0 ± 14.2 were enrolled, including114 (23.4%) diabetes. Q1 (n = 121, 24.8%), Q2 (n = 118, 24.2%), Q3 (n = 125, 25.7%), and Q4 (n = 123, 25.3%). The Q1 group exhibited characteristics of increased age, malnutrition, and a higher prevalence of diabetes. During the 48.1 months follow-up time, 197 (35.8%) died, 109 (55.3%) cardiovascular disease (CVD), 38 (19.3%) infections. Kaplan-Meier analysis revealed that both all-cause mortality and cardiovascular mortality were significantly higher in the Q1 and Q4 groups (log-rank = 24.373, p < 0.001). COX regression analysis showed that decreased TA-SUA level was an independent risk factor for all-cause mortality in PD patients after adjustment for confounding factors. Each 1 mg/dl decrease in TA-SUA level was associated with a 23.46% increase in all-cause mortality (HR = 0.81, 95% CI, 0.71-0.94; p = 0.004*). Lower serum albumin level was associated with increased all-cause mortality.

conclusionPD patients with lower TA-SUA were older and had a higher proportion of diabetes and malnourishment than those with higher TA-SUA. Long-term exposure to low TA-SUA levels was an independent predictor of all-cause and cardiovascular mortality in PD patients.
