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

purposePostoperative pneumonia (POP) is a major complication of hepatobiliary and pancreatic surgery that significantly affects patient outcomes. However, the necessity of routine preoperative spirometry to assess the risk of POP remains uncertain. We therefore evaluated whether or not omitting routine preoperative spirometry affects the postoperative outcomes, particularly the incidence of POP.

methodsThis retrospective study included 691 patients who underwent hepatobiliary and pancreatic surgeries at our institution. Patients were categorized into two groups: the pre-COVID-19 group (April 2018 to March 2020), wherein all patients underwent spirometry, and the COVID-19 group (April 2020 to March 2022), with limited spirometry. This study evaluated postoperative outcomes and risk factors for POP in both groups.

resultsNo significant differences were observed in the incidence of POP between the pre-COVID-19 and COVID-19 era groups (2.9% vs. 2.3%, p = 0.6197) or between patients with and without spirometry during the COVID-19 period (2.1% vs. 2.5%, p = 1.0000). Abnormal spirometry results were independent risk factors for POP and were significantly associated with male sex, a history of lung disease, and abnormal chest imaging findings.

conclusionsIn patients undergoing hepatobiliary and pancreatic surgery, omitting routine preoperative spirometry did not adversely affect postoperative outcomes, including POP incidence. Therefore, targeted spirometry may be acceptable.
