Feasibility and preliminary effects of a nurse-led multi-component phosphate control intervention in patients on hemodialysis: a pilot randomized trial.
Article in BMC nursing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsThis pilot trial aimed to evaluate the feasibility of a nurse-led multicomponent intervention (Targeting Intake and Pills, TIPs) using serial phosphorus metrics for patients undergoing hemodialysis treatment, and to estimate variability to inform a future definitive trial.
designThis was a pilot randomized controlled trial.
methodsThis 3-month trial, conducted in Shanghai, China, enrolled maintenance hemodialysis patients with persistent hyperphosphatemia (>1.78 mmol/L [5.5 mg/dL] over two consecutive quarters) who were receiving phosphate binder therapy. The intervention included dietary phosphate management, facilitation of binder adherence, and physician referral for dialysis adequacy optimization. Outcomes assessed included feasibility (recruitment and retention rates), serum phosphorus levels (using area-under-the-curve [AUC] and rolling averages), dietary consumption, and pruritus symptoms.
resultsOf 192 participants screened, 58 (30.21%) were eligible, and 30 (51.72%) were randomized (n = 15 per group). Participant retention was 86.67% (26/30). At follow-up, 88% of scheduled quarterly serum phosphorus measurements were completed. For the secondary, exploratory clinical outcomes, the estimated between-group difference in AUC was -0.33 (95% CI: -1.24 to 0.58), with a residual standard deviation of 1.21. For pruritus, the adjusted between-group difference was -1.53 (95% CI: -4.00 to 0.94). Dietary outcomes showed substantial variability, with residual standard deviations of 144.00 mg/day for phosphate intake, 12.67 g/day for protein intake, and 299.56 kcal/day for energy intake.
conclusionsThis pilot study demonstrated the feasibility of recruitment and data collection in hemodialysis patients. The estimates of outcome variability and the influence of baseline values provide critical information for designing a fully powered randomized controlled trial. RELEVANCE TO CLINICAL PRACTICE: The nurse-led TIPs intervention appears feasible and acceptable for use in routine nephrology care settings. However, its comparative clinical effectiveness remains to be established in a larger definitive trial.
trial registrationThe trial was registered with the Chinese Clinical Trial Registry (ChiCTR) on 2020/04/03 (clinical trial registration number: ChiCTR2000031509).
