Cross-sectional study investigating the relationship between pit recovery time and serum albumin levels in bilateral lower extremity pitting oedema.
Article in BMJ open, 2024. 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
objectivesIn this study, we re-evaluated the relationship between pit recovery time (PRT) and serum albumin levels and elucidated the factors influencing PRT.
designCross-sectional study.
settingPatients who visited the outpatient department or were admitted to a small urban hospital in Japan.
participants135 adult Japanese patients with bilateral lower extremity pitting oedema.
interventions
resultsWe found no significant correlation between lower leg PRT and serum albumin levels. Furthermore, a PRT of <40 s was largely ineffective in predicting low albumin levels. Factors influencing PRT included the diagnosis of malnutrition oedema, examinations conducted during hospitalisation, diagnosis of cardiac oedema, use of diuretics, thickness of the lower limb soft tissue, serum creatinine level, estimated right ventricular systolic pressure (RVSP), age, serum albumin level, potassium level and blood urea nitrogen to serum creatinine ratio. Notable correlations with PRT were observed in relation to lower limb soft tissue thickness, age and estimated RVSP.
conclusionsGiven that the PRT is influenced by multiple factors, its correlation with serum albumin levels is weak. Thus, predicting hypoalbuminaemia based solely on PRT is inaccurate.
