1 · What the graph read from it

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.

2 · The registry

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

Calcium ion flux following the administration of a series of neuropeptides, N6,O2'-dibutyryladenosine 3',5'-cyclic monophosphate, and serum was monitored by flow cytometry in selected lung and breast cancer cell lines and Chinese hamster ovary cell line CHO-K1. Calcium ion flux was monitored in individual cells by flow cytometry using the indicator indo-1 AM. Five groups of neuropeptides produced calcium flux changes in lung cancer cell lines and CHO-K1 cells but not in breast cancer cells. The peak increase in free calcium was reached within 10 sec of peptide administration and declined to resting levels in 70-120 sec. When two or more members of the same group were administered simultaneously, calcium flux changes were identical to that produced by each single peptide. When two or more members of different groups were administered simultaneously, an increased calcium release occurred. When identical peptides or peptides from the same group were administered sequentially after the return of calcium concentrations to resting values, no calcium flux resulted from the second peptide. When peptides from different active groups were administered sequentially, a new calcium flux occurred after each peptide. These data are interpreted to mean that members of each active group of peptides trigger a different calcium flux pathway. Thus, many such pathways and different metabolic states exist within the cell. Elucidation of calcium flux pathways in normal and cancer cells may lead to greater understanding of the nature of the malignant defect.
