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

objectiveThe American Society of Anesthesiologists (ASA) physical status classification system is a preoperative evaluation regarding the risk of anesthesia during surgery. We investigated associations of ASA scores with postoperative Patient-Reported Outcome Measures (PROMs) and long-term survival rate in patients undergoing vertebroplasty.

methodsWe retrospectively identified patients undergoing vertebroplasty for vertebral compression fractures from 2018 to 2020. PROMs were assessed using the Oswestry Disability Index (ODI) and EuroQol-5D (EQ-5D) prior to surgery and at postoperative follow-up. Patients were categorized by preoperative ASA scores (≤ 2 vs. ≥ 3). Between-group differences in postoperative changes of PROMs were compared. All-cause mortality was confirmed through March 2022. The association of ASA classification with all-cause mortality was examined using Cox-proportional hazard models.

resultsA total of 199 patients were analyzed (ASA ≤ 2, n = 95; ASA ≥ 3, n = 104). Patients with an ASA ≤ 2 experienced a greater improvement in ODI (mean [SD] -35.8 [18.7] vs. -25.5 [17.4], p = 0.001) and EQ-5D (mean [SD] 0.42 [0.22] vs. 0.33 [0.26], p = 0.042) at 12-month follow-up than those having an ASA ≥ 3. After a median follow-up of 2.2-years, patients having a higher ASA score (≥ 3 vs. ≤ 2) experienced a greater risk of all-cause mortality (HR = 3.315, 95% CI 1.330 to 8.258, p = 0.010).

conclusionA lower ASA score (≤ 2 vs. ≥ 3) was associated with a greater improvement in PROMs and better long-term survival after vertebroplasty for compression fractures. ASA classification may help identify high-risk patients, even in less invasive surgeries.
