Comparative analysis of colorectal carcinoma staging using operative, histopathology and computed tomography findings.
Article in International journal of applied & basic medical research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThe staging of colorectal carcinoma using 3 modalities viz operative, histopathology and CT scan has been subject of interest in accurately defining the extent of disease. This retrospective as well as prospective study was carried out at CMC, Ludhiana, Punjab from November 2011 to May 2014.
aimThe objective of this study was to assess the usefulness and accuracy of CT scan findings to state the extent and spread of colorectal malignancy and to correlate these findings with histopathological diagnosis.
methodA total of 31 biopsy proven patients showing variable bowel wall thickening involving the colon /rectum on CECT (Contrast Enhanced Computed Tomography) were included in the study. The tumours were staged based on the CT scan findings and were compared with the operative and histopathological findings. OBSERVATIONS: Rectum was the most common site of involvement followed by the recto-sigmoid involvement. Metastasis was observed in 5 cases out of the 31 malignant cases. Five of the 7 cases were correctly staged as T1 & T2 lesions on CT having a sensitivity of 83.3%, specificity of 92%, and positive predictive value of 71.4% and a negative predictive value of 95.8% in the diagnosis of T1 and T2 lesions. 15 of the 16 cases were correctly staged as T3 lesions. CT had a sensitivity of 88.2%, specificity of 93.8%, and positive predictive value of 93.8% and a negative predictive value of 86.7% in the diagnosis of T3 lesions. All the 8 cases were correctly staged as T4 lesions. CT had a sensitivity of 100%, specificity of 100%, and positive predictive value of 100% and a negative predictive value of 100% in the diagnosis of T4 lesions.
conclusionWe conclude that CT scan is an excellent modality in diagnosing malignant lesions of the colon and rectum.
