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

rationaleBilateral ovariectomy in female mice produces a menopausal depressive-like state but the factors responsible for the phenomenon are unknown.

objectivesWe elucidated methodological issues related to establishing this mouse model and investigated a possible mechanism underlying the depressive-like state of ovariectomized mice.

methodsWe removed both ovaries of female ICR mice at 9 weeks of age. Changes in the immobility time during the forced swimming test as a function of the time interval between ovariectomy and behavioral testing were determined on nine different days after surgery. To assess behavioral specificity, the elevated plus-maze (EPM) behavior and spontaneous activity were measured. With respect to the effect of ovariectomy on the immobility time, we compared ICR mice with three other strains of mice (C57BL/6J, DBA/2N, and CD-1). Finally, we investigated the effects of (-)-2,5-dimethoxy-4-iodoamphetamine (DOI) and (+/-)-8-hydroxy-2-(N,N-di-n-propylamino) tetralin (8-OH-DPAT) on the immobility time of ovariectomized mice.

resultsA significant effect on the prolongation of immobility was observed between 12 and 18 days after ovariectomy. Ovariectomy did not alter either the EPM behavior or spontaneous activity. Of the four strains of mice, only DBA mice did not show any significant prolongation of immobility after ovariectomy. Acute or chronic treatment with DOI (0.5 or 1.0 mg kg(-1)) significantly prevented the prolongation of immobility time, whereas acute and chronic treatments with 8-OH-DPAT (0.05, 0.5, or 1.0 mg kg(-1)) were ineffective.

conclusionThe present findings have potentially important implications for evaluating a candidate substance for the management of mood disorders in menopausal women.
