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

objectiveTo evaluate the protective effect of tramadol on renal tissue in rats with induced renal ischemia-reperfusion injury (I/R injury), and its effects on oxidative stress. MATERIAL AND

methodsThirty adult, male Wistar rats weighing 250-300 g were selected as subjects. Rats were randomized into 3 groups: group 1, sham; group 2, renal I/R injury; and group 3, renal I/R+Tramadol. In order to obtain ischemia in groups 2 and 3, renal artery was clamped for 1 h. Total oxidant status (TOS) and total antioxidant capacity (TAC) were analyzed using biochemical assays in the serum samples.

resultsTOS values were measured as 1.68±0.4 in group 1, 3.35±1.0 in group 2, and 3.49±0.9 in group 3. When group 1 was compared with group 2 and group 3, the TOS values of group 1 were significantly lower (p<0.05), whereas there was no difference between group 2 and group 3 (p>0.05). TAC values were measured as 1.65±1.4 in group 1, 1.85±0.1 in group 2, and 2.79±0.6 in group 3. The antioxidant status of group 1 was not significantly different from that of group 2 (p>0.05), whereas there was a significant difference between group 1 and group 3 (p>0.05).

conclusionsTramadol has positive effects on antioxidant levels in renal I/R injury. We think that tramadol may be used in patients who underwent renal surgery and have I/R injury risk. There is a need for studies on this subject including human series.
