Preoperative step count as a predictor of early postoperative mobility and patient-reported outcomes following lumbar spine surgery.
Article in Journal of craniovertebral junction & spine. 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
Objectives: Objective activity monitoring may provide scalable, real-world functional data in lumbar spine surgery patients. We evaluated whether preoperative daily step count predicts early postoperative ambulation and patient-reported outcomes (PROs). Materials and Methods: We performed a retrospective cohort study of adults undergoing elective lumbar decompression, discectomy, or fusion with remote monitoring of daily step counts (preoperative days 7-1 and postoperative days [PODs] 1-28) and longitudinal PROs (Patient-Reported Outcomes Measurement Information System [PROMIS] - Pain/Physical/Mental and Oswestry Disability Index [ODI] at baseline, 6 weeks, 12 weeks, 6 months, and 1 year). Patients were stratified by mean preoperative step count into low activity (<2500 steps/day) versus normal activity (≥2500 steps/day). Between-group comparisons used the Chi-square tests for categorical variables and independent t-tests for continuous variables ( Results: Forty-seven patients were included (mean age: 51.8 ± 13.7 years; body mass index: 29.85 ± 5.00), including 21 (44.7%) low-activity and 26 (55.3%) normal-activity patients. Preoperative steps were lower in the low-activity group (1354 ± 639 vs. 5148 ± 2399; Conclusions: Preoperative step count stratifies early postoperative mobility and short-term pain/disability trajectories after lumbar spine surgery. Objective activity monitoring may support perioperative risk stratification and targeted prehabilitation.
