Impact of impaired intrinsic capacity on postoperative frailty in elderly patients undergoing colorectal surgery: study protocol for a single-center, prospective, cohort study.
Article in Frontiers in aging neuroscience, 2025. 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
Introduction: Frailty is characterized by a decline in multiple physiological systems, increasing vulnerability to stressors such as surgery and anesthesia. A decline in intrinsic capacity is common among elderly populations and has been demonstrated to be a predictor of frailty in community-dwelling seniors. However, the relationship between preoperative intrinsic capacity decline and postoperative frailty in surgical patients remains unclear. Methods: This study is a single-center, prospective, cohort study. The study will recruit participants aged 60 years and above who are scheduled to undergo elective colorectal surgery. Participants will be classified into an exposed group (intrinsic capacity score ≤ 8) and a non-exposed group (intrinsic capacity score ≥ 9) according to their preoperative intrinsic capacity assessment. The primary outcome is the risk of frailty in elderly patients with impaired intrinsic capacity within one year following colorectal surgery. The secondary outcomes include postoperative pain scores, sleep quality, recovery quality, grip strength, fall risk, activities of daily living, onset time of moderately frailty, incidence of moderately frailty, and adverse events. All assessments will be conducted at predetermined intervals through face-to-face interviews during hospitalization and via telephone follow-up post-discharge. Discussion: This study aims to clarify the risk of postoperative frailty in older patients with impaired intrinsic capacity. This study seeks to enable the early identification of patients with impaired intrinsic capacity, allowing for the implementation of targeted interventions to reduce the risk of postoperative frailty.
