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

Current systemic dosages of chemotherapeutic drugs such as gemcitabine, 5-FU, cisplatin, doxorubicin are administered every 7 days over 4 cycles due to systemic toxicity. An increase in potency of the drugs will result in dosage reduction with more frequent administration and efficacy increase. Hence, we investigated how the drugs potency can be increased by combining with bromelain and N-acetylcysteine. Tumour cells (5,000/well) were seeded into a 96 well plate and treated 24 hrs later with either single agents or in combinations at various concentrations. Cell survival was assessed by the sulforhodamine B assay after 72 hours of exposure. LD 50 was determined for each treatment and the Combination Index (CI) was assessed to determine synergy using Tallarida's method. CI indicated that synergy was dependent on the concentration of the agents used and was cell line specific. For bromelain and N-acetylcysteine, certain ratio of the two agents gave very good synergy that was prevalent in almost all cell lines. Gemcitabine and 5-FU and doxorubicin reacted favourably with most concentrations of bromelain and NAC investigated. Cisplatin and oxaliplatin were not very compatible with NAC. A value of CI <0.5 indicated that the current clinical chemotherapeutic dosage can be dramatically reduced. Bromelain with NAC showed synergy in all tumour cell lines and acting synergistically with chemotherapeutic drugs. Synergistic combinations resulting in considerable dosage reduction of chemotherapeutic agents may enable more frequent treatment with higher efficacy.
