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 purpose of this study was a comparison between osteoarthritis patients with primary hip and knee replacements before, during and after the first COVID-19 lockdown in Germany. Patients' preoperative health status is assumed to decrease, owing to delayed surgeries. Costs for patients with osteoarthritis were assumed to increase, for example, due to higher prices for protective equipment. Hence, a comparison of patients treated before, during and after the first lockdown is conducted.

methodsIn total, 852 patients with primary hip or knee replacement were included from one hospital in Germany. Preoperative health status was measured with the WOMAC Score and the EQ-5D-5L. Hospital unit costs were calculated using a standardised cost calculation. Kruskal-Wallis tests and Chi-squared tests were applied for the statistical analyses.

resultsThe mean of the preoperative WOMAC Score was slightly higher (p < 0.01) for patients before the first lockdown, compared with patients afterwards. Means of the EQ-5D-5L were not significantly different regarding the lockdown status (NS). Length of stay was significantly reduced by approximately 1 day (p < 0.001). Total inpatient hospital unit costs per patient and per day were significantly higher for patients during and after the first lockdown (p < 0.001).

conclusionPreoperative health, measured with the WOMAC Score, worsened slightly for patients after the first lockdown compared with patients undergoing surgery before COVID-19. Preoperative health, measured using the EQ-5D-5L, was unaffected. Inpatient hospital unit costs increased significantly with the COVID-19 pandemic. LEVEL OF EVIDENCE: Retrospective cohort study, III.
