Age diversity among older surgically treated patients with lumbar spinal stenosis: a retrospective comparative study of early and late older adults.

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
backgroundAt present, the threshold defining older adults is 65 years, and this classification has been widely accepted globally. However, with the extension of both life expectancy and healthy life expectancy, there is a need to reconsider this age-based definition. This study compared the characteristics and surgical outcomes of older patients with lumbar spinal stenosis (LSS) between the early and late stages to clarify age diversity in this population.
methodsData collected from consecutive patients aged ≥ 65 years who underwent LSS surgery were retrospectively reviewed. All participants completed the Zurich Claudication Questionnaire, Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), and 25-Question Geriatric Locomotive Function Scale preoperatively as well as 6 and 12 months postoperatively. Frailty was evaluated using the 11-point modified frailty index. Polypharmacy was defined as the concomitant use of at least six drugs.
resultsIn total, 311 older patients with LSS were enrolled. Among them, 136 patients younger than 75 were categorized into the E group, and 175 patients aged 75 and older were categorized into the L group. Baseline characteristics, including frailty and polypharmacy, significantly differed between the groups. The frequency of effective case of surgical treatment on JOABPEQ was significantly lower for walking ability in the L group. At 1 year after surgery, the incidence of non-improvement in locomotive syndrome stages was higher in the L group than in the E group (relative risk = 1.38, 95% confidence interval [CI] = 1.08-1.78). In addition, when the L group was further divided into three subgroups based on age, the relative risk was 1.32 (95% CI = 0.99-1.76) for patients aged 75 to < 80, 1.42 (95% CI = 1.07-1.88) for those aged 80 to < 85 years, and 1.68 (95% CI = 1.16-2.45) for those aged ≥ 85.
conclusionsSignificant differences were observed in baseline characteristics and postoperative improvement of walking ability and locomotive syndrome based on age among older patients with LSS. Our findings underscore the significant age diversity among older adults, highlighting the necessity of considering each patient in a more nuanced age-specific manner rather than adopting a one-size-fits-all approach.
