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
Background: This study aimed to evaluate the impact of ketorolac on the pharmacokinetics of 5-FU and its effect on the efficacy of 5-fluorouracil (5-FU) on the HT-29 cell line. Methods: Cell culture: the HT-29 cell line was treated with different concentrations of 5-FU, ketorolac, and combination of 5-FU and ketorolac for 24 and 48 hours. The cell viability (%) was calculated by the MTT assay. Animal study: rats were randomly divided into control and pretreatment groups. The control group received physiological saline, whereas the pretreatment group received ketorolac by intraperitoneal (i.p.) injections on a daily basis for 14 days. On the 15th day, both groups received 5-FU (i.p.). Blood samples were collected at different times for HPLC analysis, and 5-FU pharmacokinetic parameters were calculated. Results: At cell culture study, in a certain concentration range, combination therapy showed synergistic effects (<0.05). However, at concentrations above this range, combination therapy showed antagonistic effects on 5-FU efficacy (<0.05). According to the pharmacokinetic analysis, pretreatment with ketorolac resulted in a significant increase in AUC, Conclusions: Combination therapy with ketorolac and 5-FU, depending on time and concentration, has a synergistic effect on reducing the viability of cancer cells. Also, ketorolac is able to alter the pharmacokinetics of 5-FU. Since there is a close relationship between pharmacokinetic parameters of 5-FU and its effectiveness/toxicity, it seems that these changes are towards creating a synergistic effect on 5-FU cytotoxicity. These results suggest the need to optimize the dose of these drugs in order to increase clinical efficacy and reduce the toxicity associated with them.
