Table 2 Comparison between the three studied groups according to initial latency and retention latency (passive avoidance test)

From: The potential value of capsaicin in modulating cognitive functions in a rat model of streptozotocin-induced Alzheimer’s disease

Passive avoidance test Group I Group II Group III F p
Initial latency (seconds)
 Min.–max. 16.0–40.0 14.0–32.0 14.0–43.0 0.490 0.620
 Mean ± SD 25.0 ± 9.43 21.0 ± 5.55 23.60 ± 8.64
Retention latency (seconds)
 Min.–Max. 300.0–300.0 25.0–50.0 130.0–300.0 83.019* < 0.001*
 Mean ± SD 300.0 ± 0.0 37.67a ± 8.76 257.0b ± 65.84
  1. Group I negative controls; Group II STZ-induced AD, capsaicin untreated group (positive controls); Group III STZ-induced AD+ capsaicin treatment group. Normally quantitative data was expressed in mean ± SD and was compared using F test (ANOVA). F,p: F and p values for ANOVA test. Sig. between groups was done using post hoc test (LSD)
  2. *Statistically significant at p ≤ 0.05
  3. aSignificantly different from the negative controls (group I)
  4. bSignificantly different from the positive controls (STZ-induced AD, capsaicin untreated) (group II)
