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
Background: Segmentectomy is increasingly performed as a surgical technique. Traditional anterior axillary line and mid-axillary line video-assisted thoracoscopic surgery (VATS) incision meets difficulties when dealing with left segment 9+10 (LS9+10), as the distance and angle of view make it uneasy to expose the trachea, blood vessels and intersegment plane. As an alternative, dorsal incision may be advantageous as which faces the key structures of LS9+10, may facilitate the management of trachea and blood vessels of LS9+10, but there was no clinical proof reported ever. This study is targeted to compare the efficacy and safety of these two incisions in segmentectomy of LS9+10. Methods: The dorsal incision is made behind the posterior axillary line, 8th intercostal space. Patients with ground glass opacity (GGO) which solid ingredients is less than 25%, locates at LS9+10, and segmentectomy of LS9+10 could ensure the cut edge were enrolled in the study and were allocated to the traditional incision group or dorsal incision group based on the parity of hospital number. Efficacy outcomes such as the duration of surgery and safety outcomes including postoperative air-leakage duration, length of hospital stay, amount of bleeding and pain score were recorded. The Independent-samples Results: A total of 68 patients were enrolled and allocated into the traditional incision group and dorsal incision group. In the traditional incision group, the average surgery time was 71.03±6.87 min (median 71.5 min), while that in the dorsal incision group was an average of 62.72±6.24 min (median 61.0 min, P=0.001). The postoperative duration of air-leakage was 2.16±1.63 and 1.36±1.33 days for traditional incision group and dorsal incision group (P=0.030), respectively. The traditional incision group had a greater length of postoperative hospital stay (3.69±1.36 days) than the dorsal incision group (3.08±1.03 days, P=0.041), when amount of bleeding and pain score showed no differences between these two groups. Data suggested a statistically significant advantage for the dorsal incision procedure. Conclusions: Dorsal incision can facilitate the segmentectomy of LS9+10, and significantly reduce the surgery time, postoperative duration of air-leakage and length of hospital stay.
