[Effect of High-frequency Chest Wall Oscillatory on Lung Function in Patient After Single Port Video-assisted Thoracoscopic Surgery Lobectomy].

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
backgroundIt has been confirmed that high-frequency chest wall oscillatory (HFCWO) is a new type of auxiliary sputum discharge device. However, up to now, the specific therapeutic effect of HFCWO is still uncertain. This study aimed to compare the changes of the sputum volume before and after the treatment of HFCWO, and to investigate the effect of HFCWO on lung function and arterial blood gas analysis after single port video-assisted thoracoscopic surgery lobectomy (S-VATS).
methodsA total of 90 patients with S-VATS lobectomy were collected in the Second Affiliated Hospital of Soochow University from January 2017 to December 2017, which were randomly divided into the experimental group with HFCWO (n=45) and the control group (n=45) with routine clapping, respectively. The sputum volume of the two groups was measured 5 days before operation. Lung function and arterial blood gas analysis was measured before and 7th days after surgery.
resultsThe sputum volume was higher in the experimental group than that of the control group after surgery, there was statistically significant difference for the first three days (P<0.05). There was no statistically significant difference between the two groups in forced expiratory volume in one second (FEV₁), forced vital capacity (FVC) and oxygen partial pressure (PaO₂) before surgery (P>0.05); Compared with those before surgery, FEV₁, FVC and PaO₂ decreased in both groups after surgery (P<0.05); However, FEV₁, FVC and PaO₂ in the experimental group were higher than those in the control group (P<0.05); There was no statistically significant difference in preoperative and postoperative partial pressure of carbon dioxide (PaCO₂) between the two groups (P>0.05).
conclusionsHFCWO can significantly increase the amount of sputum excretion, improve lung function and alleviate hypoxia status after S-VATS lobectomy. This study provides a promising approach for HFCWO toward hypoxia status after S-VATS lobectomy. .
