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 feasibility of focal cerebral ischemia and reperfusion (FCIR) surgery combined chronic unpredictable mild stress (CUMS) to simulate the post-stroke depression (PSD) state in rats.

methodsSprague-Dawley male rats were divided randomly into five groups: the normal, sham, FCIR, CUMS, and FCIR + CUMS (F/C) groups. Rats in the FCIR and F/C groups underwent an FCIR operation. Rats in CUMS and F/C groups were single-housed and exposed to CUMS for 4 weeks. Rats in the F/C group underwent CUMS for 4 weeks after FCIR surgery. The gain in bodyweight, the sugar consumption ratio in a sucrose preference test (SPT), and behavior, including spontaneous moves (SM), the duration of time spent in the center arena (duration), and the number of rearings (rearing) in an open field test (OFT), were evaluated.

resultsRats in the CUMS and F/C groups had a smaller gain in bodyweight (P < 0.05). The sugar consumption ratio was reduced significantly in the CUMS and F/C groups compared with the normal and FCIR groups (P < 0.05). The number of SM was significantly lower in the FCIR group compared with the normal group. SM, duration, and rearing were reduced significantly in the CUMS and F/C groups relative to the normal group. Furthermore, the number of rearings was lower in the F/C group compared with the CUMS group.

conclusionAnhedonia, a lack of curiosity, and inactivity were observed in the F/C rats, which exhibited depression-like symptoms after FCIR surgery.
