5 Tables/Figures

6 Use tables to highlight individual values. Use figures to highlight trends/relationships. Check your math. Provide consistent row or column summation. Keep lines to a minimum; avoid vertical lines. Use footnotes to clarify points of potential ambiguity. Check heading, labels of rows/columns/axes, and footnotes.

29 Smoking initiation rates were similar among adolescents and young adults from 1980 through 1984; from 1984 through 1989 rates increased among adolescents and decreased among young adults, (Fig). Smoking initiation rates were similar among adolescents and young adults from 1980 through 1984 (4.8-5.5% vs 4.4-5.1%); from 1984 through 1989 rates increased among adolescents and decreased among young adults, (Fig). Smoking initiation rates were similar among adolescents and young adults from 1980 through 1984 (4.8-5.5% vs 4.4-5.1%); from 1984 through 1989 rates increased among adolescents and decreased among young adults, (Fig). In 1988 and 1989 the smoking initiation rate among adolescents was about two percentage points higher than among young adults.

40 Persons aged 13-29 years accounted for 25% and 27% of heterosexual ‑ contact cases reported in 1992 and 1993, respectively. “Respectively” – see Strunk and White, p57 Can we revise this sentence without using “respectively”?

41 Persons aged 13-29 years accounted for 25% and 27% of heterosexual ‑ contact cases reported in 1992 and 1993, respectively. Persons aged 13–29 years accounted for 25% of heterosexual ‑ contact cases reported in 1992 and 27% in 1993.

45 Results (Excerpt: Neonatal Intensive Care Nurse Stressors: An American Study) The highest ratings for selected stressor items on a five-point scale (0-4) were floating out of the unit (3.38; SD=1.02; n=53), unnecessary prolongation of life (3.10; SD=1.27; n=51), emergencies/arrests (3.07; SD=1.03; n=57), and inadequate staffing (3.04; SD=1.04; n=56).

47 The most stressful factors were floating out of the unit, unnecessary prolongation of life, emergencies/arrests, and inadequate staffing. (S&W, rule 7, p7) The most stressful factors were the following: floating out of the unit, unnecessary prolongation of life, emergencies/arrests, and inadequate staffing. (S&W: Words and Expressions Commonly Misused) “Factor” – “can usually be replaced by something more direct” The most stressful situations were the following: floating out of the unit, unnecessary prolongation of life, emergencies/arrests, and inadequate staffing. NICU nurses identified the following situations as the most stressful: floating out of the unit, unnecessary prolongation of life, emergencies/arrests, and inadequate staffing.

48 NICU nurses identified the following situations as the most stressful: floating out of the unit, unnecessary prolongation of life, emergencies/arrests, and inadequate staffing (Table).
