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 research investigated the effects of different hemodialysis modalities combined with low-calcium dialysate (LCD) on mineral metabolism and vascular calcification (VC) in maintenance hemodialysis (MHD) patients with chronic kidney disease (CKD).
methodsGeneral data were collected from 192 cases of MHD patients, who were divided into 4 groups according to the randomized numerical table. Each group was given LCD treatment, and conventional hemodialysis (HD), high-flux HD (HFHD), hemodiafiltration (HDF), and HD + hemoperfusion (HP) were performed, respectively. The patients were dialyzed 3 times per week for 4 h each time, and each group was treated for 6 months. Fasting venous blood was collected. Serum interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and high-sensitive C-reactive protein (hs-CRP) levels were measured by ELISA, calcium (Ca2+), phosphorus (P), Ca2+-P product, serum creatinine (SCr), blood urea nitrogen (BUN), β2 microglobulin (β2-MG), and intact parathyroid hormone (iPTH) were measured by chemiluminescence immunoassay, serum alkaline phosphatase (ALP) was determined by turbidimetric assay, and 25-hydroxyvitamin D (25(OH)D) was measured by autoradiographic immunoassay. To assess the extent of calcification in the iliac artery and abdominal aorta, a multilayer spiral CT device was employed for abdominal scans.
resultsSerum IL-6, hs-CRP, TNF-α, Ca2+, P, Ca2+-P product, SCr, BUN, β2-MG, iPTH, and ALP levels decreased, while 25(OH)D levels increased in the four groups after treatment. The most pronounced effect on the reduction of IL-6, hs-CRP, TNF-α, Ca2+, P, Ca2+-P product, SCr, BUN, β2-MG, iPTH, and ALP was in the HD + HP group, followed by the HDF and HFHD groups, and then by the HD group. The rate of VC in the HDF, HFHD, and HD + HP groups was lower than that in the HD group, and the rate in the HD + HP group was lower than that in the HDF and HFHD groups.
conclusionThe combination of HD + HP and LCD in treating CKD with MHD is effective, evidently rectifying disruptions in serum Ca2+ and P metabolism, enhancing kidney function, lessening the body's inflammatory response, and lessening VC.
