Efficacy of lumbar orthoses after posterior lumbar interbody fusion-a prospective randomized study.
Trial report in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundLumbosacral orthoses (LSOs) are used as standard care after lumbar fusion surgery though their efficacy is unknown. The purpose of this prospective randomized controlled study was to elucidate the clinical and radiographic efficacies of LSO treatment in patients who underwent posterior lumbar interbody fusion (PLIF) of less than 3 segments.
methodsSeventy-three patients who underwent PLIF were randomly allocated to 3 groups: 1 with custom-made LSO with metallic stays (C group); 1 with ready-made LSO without metallic stays (R group), and 1 without LSO (N group). The patients in the C and R groups were instructed to wear LSO postoperatively for 3 months. Clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) score, JOA-back pain evaluation questionnaire (JOABPEQ), Roland-Morris Disability Questionnaire, and 100-mm visual analog scale for low back pain. Radiographic evaluation included intervertebral fusion rates and loss of correction postoperatively at 2 years.
resultsA significant difference in the clinical outcomes was observed only for the lumbar dysfunction domain of JOABPEQ postoperatively at 1 month (N vs C groups; 45% vs 10%, P = .03). Radiographic outcomes were not different between the groups.
conclusionsNo effect of orthosis treatment for less than 3 segments in PLIF was observed on clinical and radiographic outcomes. The type of orthosis also did not influence the outcomes. These results suggest that the use of LSO for PLIF can be simplified or is omissible except in patients with severe osteoporosis.
