Clearance of Magnesium in Peritoneal Dialysis Patients: A Single-Center Study.

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
objectiveThis retrospective study aimed to investigate the clearance of magnesium (Mg) in peritoneal dialysis (PD) patients and its influencing factors.
methodsThe demographic information, clinical characteristics and laboratory data of the patients were collected. According to the corrected serum Mg (cS-Mg) concentration, patients were divided into 3 groups including hypomagnesemia (Mg2+ < 0.77 mmol/L, group A), normal serum Mg concentration (0.77 mmol/L ≤ Mg2+ ≤1.03 mmol/L, group B), and hypermagnesemia (Mg2+ > 1.03 mmo/L, group C).
resultsOne hundred and fifteen patients were enrolled, and their mean 24 h-peritoneal Mg clearance was 39.75 ± 17.42 mg. The mean normalized peritoneal Mg clearance rate was 1.82 ± 0.82 L/day/1.73 m2. Twenty-four-hour peritoneal Mg clearance of group A was significantly lower than that of group C (p < 0.05). Bivariate correlation analysis showed that cS-Mg was positively correlated with peritoneal dialysate Mg concentration (p < 0.01). cS-Mg was negatively correlated with the normalized peritoneal Mg clearance rate (p < 0.05). The normalized peritoneal Mg clearance rate was positively correlated with prealbumin (p < 0.05), daily peritoneal protein loss (p < 0.01) and the normalized PD-creatinine clearance rate (p < 0.01). The normalized peritoneal Mg clearance rate was also negatively correlated with the normalized renal-creatinine clearance rate (p < 0.01). Furthermore, cS-Mg of patients with continuous ambulatory PD (CAPD) was significantly lower than that of patients with daytime ambulatory PD (DAPD, p < 0.01). The normalized peritoneal Mg clearance rate of patients with CAPD was significantly higher than that of patients with DAPD (p < 0.01). Moreover, among the patients with different peritoneal transport characteristics of peritoneal equilibration test, the normalized peritoneal Mg clearance rate of high average transport patients was significantly higher than that in those with low transport, low average transport and high transport (p < 0.05).
conclusionsSerum Mg could be partly cleared by PD. The peritoneal Mg clearance was positively related with serum Mg concentration, which was concentration-dependent. Peritoneal Mg clearance was negatively correlated with the residual renal function, while being positively correlated with the nutritional status and daily peritoneal protein loss. Peritoneal Mg clearance was higher in patients with high transport characteristics or CAPD.
