Scanning more corresponds to more accuracy in hemodialysis patients: 28-zone protocol's superior findings from an observational 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
aimsHypervolemia remains a problem in hemodialysis patients and is associated with hypertension, cardiovascular events and mortality. Lung Ultrasound (LUS) is a technique that detects hypervolemia via 4 different protocols depending on the number of sites checked on the chest wall. It has not been established which protocol should be preferred in the literature.
methodsThis study included 68 hemodialysis patients from one Dialysis Unit. All the patients underwent LUS with every single protocol 30 min before and after the end of the middle-week dialysis session by a nephrology trainee. Patients' ideal weight was modified based on daily clinical practice rather than ultrasound findings.
resultsSeventeen patients (25%) had ultrasound findings compatible with hypervolemia before the dialysis session, while eleven patients (16.2%) had still pulmonary congestion after the end of the session. These findings were similar to the number of patients considered hyperhydrated based on clinical criteria (10 patients). The rest protocols (8-zone, 6-zone and 4-zone protocol) considered fewer patients as hypervolemic.
conclusionsThe 28-zone protocol can effectively detect hypervolemia and even classify the degree of it, although It is a time-consuming method. However, the other protocols can detect the hypervolemia in hemodialysis patients only when severe lung congestion exists. Their usefulness is limited in daily clinical practice in hemodialysis patients. More studies should be carried out for further and more reliable conclusions.
