Effect of Depressive Symptoms on Return to Work After Lumbar Spine Fusion Surgery: A Retrospective Registry Study.
Article in Spine, 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
designRetrospective registry study.
objectiveTo investigate the influence of depressive symptoms on return to work (RTW) after lumbar spine fusion (LSF) surgery over a two-year follow-up. A secondary objective was to evaluate the development of depressive symptoms separately in patients who succeeded or failed to RTW after surgery.
backgroundDepressive symptoms are overrepresented in patients undergoing LSF surgery. The effect of depressive symptoms on RTW after LSF surgery has not yet been widely studied. MATERIALS AND
methodsA total of 348 consecutive patients available to the workforce underwent LSF surgery. Depressive symptoms were evaluated at baseline and three, 12, and 24 months postoperatively using the MHI-5. Lower scores have been shown to indicate greater depressive symptoms, and a cutoff score of ≤68 indicates current major depressive disorder (MDD). Cumulative RTW and MHI-5 scores were prospectively followed up at the aforementioned time points.
resultsBefore surgery, almost half (46%) of the patients had MDD. The presence of preoperative MDD indicated a lower RTW at two years [72% vs . 82%, adjusted HR: 0.77 (95% CI: 0.61 to 0.98)]. The probability of RTW was correlated with an increase in the MHI-5 score until the inflection point of 70, after which a further increase in the MHI-5 score no longer increased the probability of RTW. In addition, the MHI-5 score was significantly higher than baseline at three months postoperatively [13 points (95% CI: 10 to 15)] and remained higher in patients who RTW during two years. However, only a marginal increase in MHI-5 was observed in those who failed to RTW. This finding indicates fewer depressive symptoms in patients who successfully RTW.
conclusionPatients with preoperative MDD were less likely to RTW after LSF surgery. After surgery, depressive symptoms diminished in the group who did successfully RTW. LEVEL OF EVIDENCE: Level III.
