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

Background: The administration of an adequate dialysis dose is a critical aspect for ensuring the effectiveness of hemodialysis (HD) treatment and improving survival. Kt is a key indicator to evaluate the dose, with two targets: based on sex (Kt-Sx) and body surface area (Kt-BSA). Methods: This retrospective study (2022-23) was conducted across 15 HD centers analyzed 1829 prevalent patients and 317 842 HD sessions. Results: It was found that 65.9% met both Kt targets, 21.2% met only Kt-Sx and 12.9% met neither. Failure to meet both of the targets was associated with being male, older age, shorter time on HD, higher comorbidity, low body mass index, use of a catheter, shorter sessions, conventional HD, low flow rates and small membranes. Meeting at least the Kt-Sx target was associated with a 41.6% reduction in 24-month mortality risk, and an even more favorable association was observed when both targets were met, reducing the risk by 61.7%. Conclusions: These findings highlight the importance of personalizing dialysis considering both sex and BSA, particularly in overweight or obese patients, to improve survival.
