Effect of pressure-controlled ventilation and volume-controlled ventilation for laparoscopic surgery in the Trendelenburg position: a systematic review and meta-analysis.
Review in Perioperative medicine (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundVolume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) are commonly used in laparoscopic surgery in the Trendelenburg position, and pressure-controlled ventilation volume guaranteed (PCV-VG) has been increasingly used recently. However, there is still no consensus on the optimal ventilation mode. Therefore, a systematic review and meta-analysis were conducted to compare the effects of different ventilation modes for laparoscopic surgery in the Trendelenburg position.
methodsMultiple databases were searched for randomized controlled trials published before December 2024 to compare the effects of PCV, PCV-VG, and VCV in patients in the Trendelenburg position who underwent laparoscopic surgery. The primary outcomes included peak airway pressure (Ppeak), plateau airway pressure (Pplat), dynamic compliance (Cdyn), and blood gas analysis.
resultsSixteen studies were included in this meta-analysis. PCV [Ppeak, 15‒40-min post-pneumoperitoneum and Trendelenburg position (T2): mean difference (MD) - 4.28, 95% confidence interval (CI) - 5.91 to - 2.64, P < 0.01; 60-min post-pneumoperitoneum and Trendelenburg position (T3): MD - 4.51, 95% CI - 5.41 to - 3.6, P < 0.01; 120-min post-pneumoperitoneum and Trendelenburg position (T4): MD - 5.63, 95% CI - 7.35 to - 3.91, P < 0.01; Cydn, T2: MD 3.15, 1.53 to 4.77, P = 0.0001; T3: MD 2.78, 95% CI 1.43 to 4.14, P < 0.01] and PCV-VG (Ppeak, T2: MD - 3.99, 95% CI - 7.2 to - 0.78, P = 0.01; T3: MD - 3.46, 95% CI - 6.5 to - 0.42, P = 0.03; Cydn, T3: MD 4.44, 95% CI 2.23 to 6.66, P < 0.01; T4: MD 3.61, 95% CI 1.31 to 5.91, P = 0.002) significantly reduced Ppeak and improved Cydn compared with VCV after pneumoperitoneum and Trendelenburg position. PaO
conclusionsOur meta-analysis suggests that in laparoscopic surgery in the Trendelenburg position, PCV or PCV-VG can provide a lower Ppeak and higher Cdyn throughout surgery but cannot offer better oxygenation than VCV. PCV or PCV-VG might be optimal for laparoscopic surgery in the Trendelenburg position.
