Chronic nicotine normalized the density of GABAergic inputs in Tg CHRNA5/A3/B4 (p = 0.002, Figure 2c-d) and compensated for their E/I imbalance (stratum radiatum p = 0.003; stratum oriens p = 0.039, Figure 2e).
However, the reduction of VGAT exceeded the reductions of VGLUT1 puncta and thus, the ratio of glutamatergic vs. GABAergic input was increased in the CA1 region of Tg CHRNA5/A3/B4 mice, causing an E/I imbalance (stratum radiatum p = 0.004, stratum oriens p = 0.007, Figure 2e).
45 Because the design is to randomise individuals to groups within PCP strata, some baseline imbalance in the outcome might occur; in this case, the basic analytic approach will be analysis of covariance (ANCOVA) model that adjusts for baseline values of the outcome, as well as for the design feature of clustering.
Since we did not have the proportion of population vaccinated per strata during the campaigns, calculating overall vaccination coverage without taking this into account may have resulted in less accurate results if there were great imbalance between strata.
To minimize imbalance over several strata with odd numbers of clusters, these strata were paired, and clusters were alternately allocated to either training or control, the first cluster being allocated to either training or control depending on the flip of a coin.

Radiotherapy and chemotherapy reduce the skin's tolerance to cosmetic products, and this has been attributed to an imbalance in the stratum corneum, which ultimately disrupts skin barrier function.
To minimize imbalance over several strata with a number of clusters no divisible by five, the SAS macro was programmed to start the cyclic assignment by assigning one of the colors at random (with probability 1/5).
Since moderate imbalances have been shown to be of no influence, we assumed a constant cluster size within each stratum associated with the Pareto's imbalance.
In the > 65% predicted stratum, in which there was no such imbalance in lung function at baseline, a greater magnitude of effect was observed with FF 200 μg (+227 mL) compared with FF 100 μg (+134 mL).
