Lung and blood perioperative metalloproteinases in patients undergoing oncologic lung surgery: Prognostic implications.
Trial report in Thoracic cancer, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02168751 (STUDY OF PULMONARY AND SYSTEMIC INFLAMMATORY RESPONSE SECONDARY TO LUNG RESECTION SURGERY USING INTRAVENOUS ANESTHESIA VERSUS INHALATION ANESTHESIA WITH HALOGENATED AGENTS), which is not on this map.

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.
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.

Abstract
backgroundMetalloproteinases (MMPs) have been reported to be related to oncologic outcomes. The main goal of the study was to study the relationship between these proteins and the long-term prognosis of patients undergoing oncologic lung resection surgery.
methodsThis was a substudy of the phase IV randomized control trial (NCT02168751). We analyzed MMP-2, -3, -7, and -9 in blood samples and bronchoalveolar lavage (LBA) and the relationship between MMPs and long postoperative outcomes (survival and disease-free time of oncologic recurrence).
resultsSurvival was longer in patients who had lower MMP-2 levels than those with higher MMP-2 in blood samples taken 6 h after surgery (6.8 vs. 5.22 years; p = 0.012) and MMP-3 (6.82 vs. 5.35 years; p = 0.03). In contrast, survival was longer when MMP-3 levels were higher in LBA from oncologic lung patients than those with lower MMP-3 (7.96 vs. 6.02 years; p = 0.005). Recurrence-free time was longer in patients who had lower MMP-3 levels in blood samples versus higher (5.97 vs. 4.23 years; p = 0.034) as well as lower MMP-7 (5.96 vs. 4.5 years; p = 0.041) or lower MMP-9 in LBA samples (6.21 vs. 4.18 years; p = 0.012).
conclusionMMPs were monitored during the perioperative period of oncologic lung resection surgery. These biomarkers were associated with mortality and recurrence-free time. The role of the different MMPs analyzed during the study do not have the same prognostic implications after this kind of surgery.
