High-Frequency Global Postoperative Status PROMs Track Pain Peaks and Analgesic Use After Degenerative Lumbar Spine Surgery.
Article in Global spine journal, 2026. 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
Study DesignProspective observational cohort study.ObjectiveStandard postoperative follow-up often fails to capture rapid fluctuations in symptoms after degenerative lumbar spine surgery. This study evaluated the construct validity of a high-frequency, low-burden "Global Postoperative Status" item as an exploratory measure of concurrent early post-discharge recovery burden.MethodsProspective observational cohort study of 257 patients undergoing surgery for lumbar disc herniation or spinal canal stenosis who contributed 1627 postoperative status assessments over 6 weeks via secure mobile surveys every 2-3 days. Construct validity was examined through associations with pain-peak frequency, pain-peak intensity (0-10), analgesic use, and wound pain. Because peak intensity was conditionally collected only when pain peaks were reported, the primary mixed-effects complete-case model included 209/1627 assessments (82 subjects); broader sensitivity analyses used larger available-case datasets.ResultsWorse Global Status scores were consistently associated with greater concurrent pain burden. Median status was 60 (IQR 50-80) when no pain peaks were reported vs 40 (IQR 20-50) when pain peaks occurred >5/day. Mean status was 67.2 without analgesics and 41.9 with combined opioid plus non-opioid analgesics. Status correlated inversely with pain peak intensity (Spearman rho = -0.53,
