1 · What the graph read from it

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.

2 · The registry

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

purposeThere are many reports about the risk factors for recurrence after lumbar disc surgery. However, there are none about whether lumbosacral transitional vertebrae (LSTV) are associated with recurrent lumbar disc herniation (LDH). We investigated various risk factors for recurrent LDH after discectomy including LSTV.

methodsA total of 119 patients who had undergone a discectomy for L4-5 disc herniation were evaluated with a minimum follow-up of two years. Clinical parameters including age, gender, body mass index (BMI), and smoking status, and radiological parameters including type of herniated disc, degree of disc degeneration, LSTV, and sagittal range of motion (SROM) in flexion-extension radiography were evaluated. SROM was measured by the difference of the lordotic angle between the flexion and extension view.

resultsRecurrent disc herniation at L4-5 developed in 21 (17.6%) of the 119 patients. The mean period between primary surgery and recurrence was 17.6 ± 21.1 months. LSTV was found in 11 (52.4%) of the 21 patients who had recurrence and seven (7.1%) of the 98 patients in the non-recurrent group. SROM at L4-5 was 11.68 ± 4.24° in the recurrent group and 9.04 ± 3.65° in the non-recurrent group with a significant difference (p = 0.004). Multiple logistic regression analyses confirmed that LSTV and a larger SROM were significant risk factors for recurrent disc herniation at L4-5.

conclusionsLumbosacral transitional vertebrae and a hypermobile disc in flexion-extension radiography were found to be risk factors for recurrent lumbar disc herniation.
