Mortality in patients older than 65 years undergoing surgery for degenerative lumbar spine disease: a comparison with the general population.
Article in BMC geriatrics, 2024. 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
backgroundThe increased life expectancy and prevalence of spondylarthrosis have led to a growing frequency of spinal surgery in older people. This study aims to assess whether there is an excess mortality concerning that expected in the general population associated with surgical procedures performed in patients over 65 years old for a degenerative disease of the lumbar spine.
methodsAll patients aged 65 years or older undergoing surgery at a single center between 2009 and 2019 for lumbar spine degenerative disease were included. Standardized mortality ratios (SMRs) were estimated to compare the mortality risk with the expected in the Spanish population for the same age, gender, and calendar-period. Multivariable Cox analysis was employed to determine risk factors of mortality.
resultsA total of 411 procedures were analyzed. The mean age was 72.6 years old. SMR was 0.67 (CI 95% 0.54-0.84). That benefit was significant in women after gender stratification. Patients operated on between 65-84 years old had a lower mortality rate than that expected for the general population. For patients aged 85 or older, the observed mortality was not different from that expected in the general population. Multivariable Cox analysis observed an association between higher mortality and the variables age, male, and Charlson comorbidity index score.
conclusionsCompared with the general population, patients over 65 years old who underwent spinal surgery for degenerative disease of the lumbar spine experienced a reduction in mortality. This effect was particularly significant in women and patients aged 65-84 years. Age, male gender, and Charlson comorbidity index score were associated with higher mortality risk.
