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

CONTEXT AND

objectiveCOVID-19 has become the most relevant medical issue globally. Despite several studies that have investigated clinical characteristics of COVID-19 patients, no data have been reported on the prevalence of vertebral fractures (VFs). Since VFs may influence cardiorespiratory function and disease outcomes, the aim of this study was to assess VFs prevalence and clinical impact in COVID-19. DESIGN AND PATIENTS: This was a retrospective cohort study performed at San Raffaele Hospital, a tertiary health care hospital in Italy. We included COVID-19 patients for whom lateral chest x-rays at emergency department were available. VFs were detected using a semiquantitative evaluation of vertebral shape on chest x-rays.

resultsA total of 114 patients were included in this study and thoracic VFs were detected in 41 patients (36%). Patients with VFs were older and more frequently affected by hypertension and coronary artery disease (P < 0.001, P = 0.007, P = 0.034; respectively). Thirty-six (88%) patients in VFs+ group compared to 54 (74%) in VFs- group were hospitalized (P = 0.08). Patients with VFs more frequently required noninvasive mechanical ventilation compared with those without VFs (P = 0.02). Mortality was 22% in VFs+ group and 10% in VFs- group (P = 0.07). In particular, mortality was higher in patients with severe VFs compared with those with moderate and mild VFs (P = 0.04).

conclusionsVFs may integrate the cardiorespiratory risk of COVID-19 patients, being a useful and easy to measure clinical marker of fragility and poor prognosis. We suggest that morphometric thoracic vertebral evaluation should be performed in all suspected COVID-19 patients undergoing chest x-rays.
