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

Background: Prior single-center reports advocate for use of diagnostic peritoneal aspiration or lavage (DPA/DPL) to identify blunt trauma patients (BTPs) with intra-abdominal hemorrhage who require emergent surgery. Despite this, concerns exist over the potential for DPA/DPL to delay transfer to the operating room (OR). We hypothesized that DPA/DPL application in severely hypotensive BTPs would lead to increased OR transfer time and in-hospital mortality. Methods: The 2017-2019 TQIP database was queried for adult BTPs presenting with severe hypotension (systolic blood pressure <70 mmHg) who underwent any operative intervention within two-hours. Using a 1:2 propensity-score model, patients who underwent DPA/DPL within one-hour of arrival were compared with those who did not, controlling for age, sex, comorbidities, ≥6 units of packed red cells within 4 h, and injury profile. Results: From 5514 patients, 62 (1.1 %) underwent DPA/DPL. We matched 52 DPA/DPL patients to 104 patients not undergoing DPA/DPL. There were no differences in the matched variables between cohorts (all p > 0.05). Compared to those not undergoing DPA/DPL, patients undergoing DPA/DPL had a higher rate/risk of in-hospital complications (59.6 % vs. 39.4 %, p = 0.02) (OR 2.27, CI 1.15-4.47, p = 0.02) but statistically similar rate/risk of death (65.4 % vs. 50.0 %, p = 0.07) (OR 1.89, CI 0.95-3.76, p = 0.07). Time to OR was similar between both groups (DPA/DPL 39 min vs. non-DPA/DPL 42 min, p = 0.87). Conclusion: DPA or DPL used within the first hour of arrival does not appear to delay time to OR and does not increase risk of death. This challenges concerns over potential DPA/DPL-associated delays and heightened mortality risks.
