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

purposeThe aim of this study was to investigate rates, causes, and risk factors of unplanned hospital readmissions (UHR) within 30 days, 90 days, 1 year and 2 years after metastatic spine tumour surgery (MSTS) to augment multi-disciplinary treatment planning and improve patient education.

methodsWe retrospectively reviewed 272-patients who underwent MSTS between 2005 and 2016. Hospital records were utilised to obtain demographics, oncological, procedural details, and postoperative outcomes. All UHR within 2 years were reviewed. Primary outcomes were rates, causes, and risk factors of UHR. Risk factors for UHR were evaluated utilising multivariate logistic regression analysis.

resultsThirty-day, 90 day, 1 year, and 2 year UHR-rates after MSTS were 17.2%, 31.1%, 46.2%, and 52.7%, respectively. Lung cancer primaries had the highest UHR-events (24.7%) whilst renal/thyroid displayed the least (6.6%). Disease-related causes (16.2%) were the most common reason for readmissions across all timeframes, followed by respiratory (13.7%) and progression of metastatic spine disease (12.7%). Urological conditions accounted for majority of readmissions within 30-days; disease-related causes, symptomatic spinal metastases, and respiratory conditions represented the most common causes at 30-90 days, 90 days-1 year, and 1-2 years, respectively. An ECOG >1 (p = 0.057), CCI >7 (p = 0.01), and primary lung tumour (p = 0.02) significantly increased UHR-risk on multivariate analysis.

conclusionSeventy-four percent of patients had at least one UHR within 2 years of MSTS and majority were secondary to disease-related causes. Majority of first UHR occurred between 30 and 90 days post-surgery. Local disease progression and overall disease progression account for the highest UHR-events at 90 days-1 year and 1-2 year timeframes, respectively. We define UHR in specific timeframes, thus enabling better surveillance and reducing unnecessary morbidity.
