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

backgroundThe present study ascertained the capacities of crude aqueous and ethanolic leaf extracts of Acanthus montanus (ACMO), Asystasia gangetica (ASGA), Emilia coccinea (EMCO), and Hibiscus rosasinensis (HIRO), as well as their combinatorial formulations to ameliorate hyperglycemia in Type I diabetic rats. MATERIALS AND

methodsHyperglycemia was induced by single intraperitoneal injection of alloxan monohydrate in phosphate buffer saline (PBS) solution (pH = 7.4) dosage = 120 mg/kg; bw. Individual hyperglycemic rats (HyGR) received separate doses of either 20 mg/kg bw/24 h of ACMO, ASGA, EMCO or HIRO, as well as their combinatorial formulations (AAEH) for 14 days. Preparation of aqueous extracts (AQx) and ethanolic extracts (ETHx) of the four herbal samples was according to standard methods. Blood samples were drawn from 12 h post-fasted rats at regular intervals of 24 h for 14 days and measured for fasting blood glucose concentration (FBGC) using the glucose oxidase spectrophotometric method.

resultsCumulatively, ETHx of the herbal samples exhibited the greater capacity to lower FBGC in HyGR than that of the AQx. ETHx of AAEH exhibited the highest capacity to lower FBGC in HyGR by 53.55 ± 1.04%, whereas AQx of EMCO exhibited the lowest capacity to lower FBGC, which corresponded to 36.19 ± 0.88%.

conclusionThe study showed that ETHx of the herbal samples were comparatively more potent than the corresponding AQx as agents of glycemic control and for the management of hyperglycemia. Furthermore, the combination of the herbal extracts synergistically improved the therapeutic potentials of the individual herbal extracts.
