Evaluation of gallbladder lipid level during carcinogenesis by an infrared spectroscopic method.
Article in Digestive diseases and sciences, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundFourier transform infrared (FTIR) spectroscopy is sensitive to the molecular composition of tissue and has the potential to identify premalignant tissue. Our previous studies found that the lipids band of FTIR decreased in malignant tissues compared to normal tissue but increased in the cell line.
aimTo investigate the change of lipids during carcinogenesis in the gallbladder by FTIR spectroscopy.
methodsThe tissue from 12 malignant samples and 10 normal samples together with their corresponding tissue plasma membrane and gallbladder cancer cell lines were observed by FTIR.
resultsSpecific changes of lipids were observed in the FTIR spectral features of tissue, cell, and plasma membrane. The CH3 stretching band at 2,957 cm(-1) and the CH2 stretching bands at 2,853 cm(-1) decreased in the malignant tissue but increased in the tissue plasma membrane; the C-O stretching band at 1,740 cm(-1) disappeared in the malignant tissue but significantly increased in the tissue plasma membrane. The intensity of these bands all increased in the cancer cell line. The ratio of intensity (I) of 1,460 cm(-1)/1,398 cm(-1) was smaller in malignant tissue and the tissue plasma membrane.
conclusionsLipids were increased in the plasma membrane during carcinogenesis of the gallbladder; the ratio of intensity (I) 1,460 cm(-1)/1,398 cm(-1) could be a marker to diagnose cancer by FTIR.
