    “…Independent risk factors related to ICC survival and recurrence were assessed by the Cox proportional hazards models. Here, we identified that CTLA-4(+) lymphocyte density was elevated in ICC tumors compared with peritumoral hepatic tissues (P <.001), and patients with a high density of CTLA-4(+) tumor-infiltrating lymphocytes (TILs(CTLA-4 High)) showed a reduced overall survival (OS) rate and increased cumulative recurrence rate compared with patients with TILs(CTLA-4 Low) (P <.001 and P = .024, respectively). …”

    “…We derived (1) the total time participants spent in activity categories—sleep, sedentary, light activity, and MVPA—on average per day; (2) time spent in sedentary bouts of short (1 to 15 minutes), medium (16 to 40 minutes), and long (41+ minutes) duration; and (3) MVPA bouts of very short (1 to 9 minutes), short (10 to 15 minutes), medium (16 to 40 minutes), and long (41+ minutes) duration. We used Cox proportion hazards regression to estimate the association of spending 10 minutes more average daily time in one activity or bout length category, coupled with 10 minutes less time in another, with all-cause mortality. …”

    “…Among those with an index hospital admission for MI, stroke or HF, we developed Sankey plots to describe and visualize sequences and trajectories of service use (none, re-hospitalization, community care, residential care, death) in the 12 months following discharge. We used Cox proportional hazards models to estimate hazard ratios (HRs), for commencing community care and entering residential care (and the other outcomes) within 3, 6 and 12 months, compared to a matched group without MI, stroke or HF. …”

    “…Survival rates at 1, 2, 3, 4 and 5 years after HIV registration were 88.2% (95% CI 87.6–88.7%), 85.3% (95% CI 84.6–85.9%), 82.9% (95% CI 81.9–83.4%), 81.3% (95% CI 80.5–82.0%) and 75.1% (95% CI 73.5–76.8%), respectively. The Cox proportional hazards model showed that all-cause mortality was associated with a history of ART switching (HR = 7.06, 95% CI 4.53–11.00), major opportunistic infections during ART (HR = 1.93, 95% CI 1.35–2.77), baseline CD4 count ≤ 200 vs. > 500 cells/mm3 (HR = 4.00, 95% CI 1.45–11.11), age ≥ 50 vs. < 30 years (HR = 1.77, 95% CI 1.12–2.78), and receiving nevirapine-based regimens(HR = 1.43, 95% CI 1.04–1.97). …”
