Relative validity of a self-dietary assessment nutrition application compared with a 3-day food record in non-dialysis chronic kidney disease: A prospective 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
Accurate and repeated dietary assessment is essential for nutritional management in chronic kidney disease (CKD); however, conventional methods, such as the 3-day food record, are burdensome for routine clinical use. Digital self-administered dietary assessment tools may offer a practical alternative; however, validation data in non-dialysis CKD, particularly among Asian populations, remain limited. This study aimed to evaluate the relative validity of a locally adapted digital self-dietary assessment application (Nutrirodcal) compared with a 3-day food record in patients with non-dialysis CKD. This prospective single-center study enrolled adults with non-dialysis CKD stages 3-5. Participants completed both a 3-day food record (reference method) and Nutrirodcal every 4 weeks for 12 weeks. Correlations between the two methods were assessed for energy, macronutrients, minerals, and fluid intake. Changes in nutritional status, biochemical parameters, and body composition were assessed as secondary outcomes. Twenty participants completed the study. At week 12, Nutrirodcal showed moderate-to- strong correlations with the 3-day food record for energy, protein, sodium, potassium, calcium, and phosphorus intake (Spearman
