Inflammatory low back pain-associated malignancies mimicking spondylarthritis.

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
objectivesInflammatory low back pain (IBP) is a typical feature of spondylarthritis (SpA). IBP can be caused by infections, drugs, and different malignancies. Among cancers, hematologic malignancies and solid tumors can cause IBD either paraneoplastically or through metastasis. In this study, we aimed to present the demographic and clinical characteristics of our patients who presented with IBP in the last 10 years and whose final diagnosis was malignancy.
methodsThirty-four patients who presented with inflammatory low back pain in the last 10 years and were diagnosed with malignancy as the final diagnosis were included in the study. Thirty-six patients, diagnosed as axial SpA, with similar age-sex ratio of 1:1 from each center were included as the control group.
resultsHematologic malignancies were multiple myeloma, acute leukemia, and lymphoma in descending order. Solid tumors were breast cancer, lung cancer, bone tumors, prostate, colon, embryonal carcinoma, and malignancy of unknown primary. In malignancy-related low back pain, the hematologic/solid ratio was similar (18/16), the interval between symptom and diagnosis was shorter, and biomarkers' results such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum lactate dehydrogenase (LDH) levels were significantly higher than the control group.
conclusionMalignancy-related low back pain differs from SpA patients with a more severe clinical picture, higher acute phase reactants levels, and higher LDH values. Malignancies must be kept in mind in the differential diagnosis, and in order to validate our findings, the results of larger case series are needed, especially in terms of causative malignancies. Key Points • In malignancy-related inflammatory low back pain, the hematologic/solid ratio was similar, the interval between symptom and diagnosis was shorter, and acute phase reactant levels and LDH levels were significantly higher. • Malignancy-related inflammatory low back pain differs from axial SpA patients with a more severe clinical picture, higher acute phase reactants levels, and higher LDH values. • Malignancies must be kept in mind in the differential diagnosis of axial SpA.
