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

Study designSystematic review and meta-analysis.ObjectiveThis systematic review and meta-analysis compared cervical laminoplasty (LP) with laminectomy and fusion (LF) for the treatment of degenerative cervical myelopathy (DCM), focusing on healthcare costs and patient-centered outcomes.MethodsA systematic review of EMBASE and Medline (inception to September 2024) identified studies comparing LP and LF for multilevel DCM. Outcomes included return-to-work (RTW), direct treatment costs, and changes in pain and opioid use. Meta-analyses were performed using random-effects models to estimate pooled mean differences (MD) between treatment arms and mean per treatment for study outcomes. Study quality was assessed with the Newcastle-Ottawa Scale.ResultsTwelve retrospective cohort studies (7581 patients; LP: 1,848, LF: 5733) met inclusion criteria. After appraising the included studies, we determined that 25% were of high quality, 67% were of moderate quality, and 8% were of low quality. LF had higher treatment costs ($74,772.8 USD, 95% CI $29,503.72-$120,041.88) than LP ($52,109.07 USD, 95% CI $12,234.14-$91,985.43), with an MD of -$21,620.69 USD (95% CI -$35,215 to -$8025.53, I
