A cross-sectional study investigating the relationship between pit recovery time and serum albumin levels in bilateral lower extremity pitting oedema

Objectives: In this study, we re-evaluated the relationship between pit recovery time (PRT) and serum albumin levels and elucidated the factors influencing PRT.
Design: Cross-sectional study.
Setting: Patients who visited the outpatient department or were admitted to a small urban hospital in Japan.
Participants: 135 adult Japanese patients with bilateral lower extremity pitting oedema.
Interventions:
Primary and secondary outcome measures: This study assessed the correlation between PRT and serum albumin levels, calculated the predictive accuracy for identifying a group with low albumin levels when the PRT of the lower leg was < 40 s, and identified variables that influence PRT.
Results: We 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, diagno..., Study design: This was a cross-sectional study in a single hospital.
Study population: This study included patients aged 15 years or older (to exclude children) who visited the outpatient department or were admitted to the Department of Internal Medicine at the Kameyama Municipal Medical Centre in Japan from 1 May 2021 to 31 March 2023. We recruited patients who exhibited pitting oedema distal to the knee joint. We excluded patients with oedema in unilateral lower limb, significant asymmetry in oedema between the left and right sides, non-pitting oedema, oedema due to localised skin inflammation or injury (such as cellulitis, burns, and anaphylaxis), undergoing dialysis, and individuals with critical life-threatening conditions who did not have the time for PRT measurement or examination. Based on a prior study by Henry et al., we estimated that our sample size should be more than 126 cases. The calculation method was as follows: first, we inferred data from the plot diagram of their st..., , # Data from: A cross-sectional study investigating the relationship between pit recovery time and serum albumin levels in bilateral lower extremity pitting oedema

This is a dataset from a cross-sectional study that examined the correlation between Pit recovery time(PRT) and serum Albumin levels in patients presenting with bilateral lower extremity pitting oedema. This study included patients aged 15 years or older who visited the outpatient department or were admitted to the Department of Internal Medicine at the Kameyama Municipal Medical Centre in Japan from 1 May 2021 to 31 March 2023. Data collected from the medical interview, physical examinations, laboratory tests and a transthoracic echocardiography.
