2. What to expect today? Core modules • Introduction • Generalprinciples • Specifictechniques • Title/Abstractdrafting • Finding out relevantliterature, and Introductiondrafting • Nuts & boltsofstatistics and Methodsdrafting • Practicalsession 1 – Appraisalof a publishedarticle

3. Whatisyour goal in preparinganarticle Let’s think backwards…

4. What is your goal in preparing an article • The main goals in preparing a manuscript are full reporting and disclosure of • relevant aspects of your study • Isthereanyriskofbias? • What are the findings? • Do yourfindingsapplyto the mycurrentclinicalproblem?

5. Internal validity appraisalaccording to The Cochrane Collaboration • 4 MAIN TYPES OF BIAS POTENTIALLY UNDERMINING STUDIES • Ascertainment bias • Non-uniform adjudication of events • Attrition bias • Non-uniform follow-up or compliance to treatment • Performance bias • Non-uniform performance of corollary treatments • Selection bias • The non-random allocation of pts one of the treatment groups http://www.cochrane.org

6. The EBM 3-step approach How your article should be appraised, in three steps: Step 1 – Are the results of the study (internally) valid? Step 2 – What are the results? Step 3 – How can I apply these results to patient care?

31. Generaltips • Use “men” and “women,” not “males” and “females” (except when male and female are used as adjectives, e.g., male patients) • Use “died,” not “expired” • Use “humanely killed” or “killed” for animal studies, not “sacrificed” • Replace “prior to” with “before” • Patients are not implanted, i.e., “Patients who had the Jarvik 2000 implanted,” not “The implanted patients…” • Be careful of “due to” and “because of.” Use “due to” only when you could substitute “caused by” • Recovery of brisk flow was due to thrombectomy. • Because of thrombectomy, recovery of brisk flow occurred. • Consult the AMA Style Manual

32. Neverthrowaway a goodsentence • “There is no good writing…… only good re-writing” • Rationale: We are better at editing than writing • Methods of conserving sentences: • Write about the same thing • Use similar methods • Dictation

33. Generaltips • Include one thought per sentence, one idea per paragraph • Use active voice whenever possible • Keep words simple • Be as succinct as possible • Avoid adjectives, too much description • Keep sentences short (< 22 words) and clear • Use subject-verb-object constructions: • Of the 22 patients, 5 (22.7%) reported rectal bleeding

34. Generaltips • Use transitions and key words • Outline • Consult a statistician • Install spell-check software • Consult grammar and writing websites • Buy the AMA Manual of Style • Hire an editor • Remember the question

35. Tipsforbetterwriting: words • Simple words are better than long ones • Concrete terms are better than abstract ones • Specific terms are better than general ones

36. Tipsforbetterwriting: grammar • Avoid wordiness • Know when to use active & passive voice • Avoid faulty parallelism • Paragraphs should hang together • Paragraphs should have transitions

37. Phrases “The device, with long-term durability and reliability, is enhanced by the simplicity of its design and the clinical quality of its implantable platform. The ease of the prosthesis implantation in all patients, that enables avoidance of recoil, with the superior elastic properties and the extreme biocompatibility, are unique to this technology.”

38. Phrases “The device, with long-term durability and reliability, is enhanced by the simplicity of its design and the clinical quality of its implantable platform. The ease of prosthesis implantation in all patients, that enables avoidance of recoil, with the superior elastic properties and the extreme biocompatibility, are unique to this technology.” NO!

39. Phrases “The device, with long-term durability and reliability, is enhanced by the simplicity of its design and the clinical quality of its implantable platform. The ease of prosthesis implantation in all patients, that enables avoidance of recoil, with the superior elastic properties and the extreme biocompatibility, are unique to this technology.” “The simplicity of its design and the clinical quality of its implantable platform enhance the durability and reliability of the device. The prosthesis is easy to implant in all patients. Moreover, it effectively prevents recoil, hassuperior elastic properties and isextremely biocompatible. All these characteristics make this novel stent unique among the others” NO!

40. Format • Double space • Each section on a separate page • Use subheadings (in Methods, Results) • Page numbers on the right (bottom..or top) • Make sure font size and type consistent • Format the documents 2.0 to 3.0 mm form the top, bottom, sides

41. Tense in scientific English • Present tense - previously published information accepted as fact • Spatial resolution of MR microscopy can reach 3 microns [ref]. • Present tense - refer to other parts of your document • Figure 4 shows a diffusion-weighted image. • Past tense - methods and results/actions • Rats were anesthetized with isoflurane. • All animals exhibited significantly diminished learning capacity... • Past perfect - action that happened before other past action • Group 2 rats had been housed individually prior to the beginning of the study • Present perfect - action recently completed or continuing to the present • Since 1991, researchers at the Montefiore Medical Center have collaborated with more than thirty investigators at other institutions.

42. Editing • Does it make sense? • Is the writing clear? • Are there obvious factual errors? • Check for vague or ambiguous statements • Check for wordiness • Check for errors in grammar, spelling, punctuation, capitalization, and follow the journal’s rules

43. Questions?

44. Take home messages • When designing and drafting your manuscript, remember to plan in advance and revise many times • Keep it simple and active • Avoid jargon and try to sell your message/product in every sentence or paragraph
