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
Lung cancer is the first leading cause of cancer death worldwide. oxysterol-binding protein-like 2 (OSBPL2), is a lipid transport protein regulating cholesterol homeostasis. Here, we clarified the previously unreported role of OSBPL2 in lung cancer stemness properties. We observed that OSBPL2 reduced cholesterol content by HPLC-MS. It inhibited the accumulation of lipid droplets (LDs) in lung cancer. OSBPL2-mediated lipid transportation significantly suppressed tumor sphere formation, stemness markers expression and in vivo tumorigenesis and tumor metastasis. In clinical specimens, we also demonstrated that OSBPL2 repressed the expression of Lung cancer stem-like cells (LCSCs) markers-ALDH1A1, CD133 and Nanog. The level of OSBPL2 was negatively correlated with malignant of lung cancer, such as tumor stage progression and lymph node metastasis. Taken together, these findings illustrated that OSBPL2-mediated lipid transportation inhibited the stemness and aggressiveness of lung cancer cells. OSBPL2 was a potential therapeutic target to develop novel cancer-preventive compound.
