What are the effects of drug treatments for acute vulvovaginal candidiasis in non-pregnant symptomatic women? | |||||||||
6 (1092) | Clinical cure rates | Oral fluconazole versus oral itraconazole | 4 | −2 | 0 | 0 | 0 | Low | Quality point deducted for weak methods and incomplete reporting of results |
3 (712) | Clinical cure rates | Intravaginal imidazoles versus placebo | 4 | −1 | 0 | −1 | 0 | Low | Quality point deducted for no ITT analysis; directness point deducted for high rates of attrition, especially in the placebo arm |
22 (at least 790 women) | Clinical cure rates | Intravaginal imidazoles versus each other | 4 | −2 | 0 | 0 | 0 | Low | Quality points deducted for no ITT analysis and for incomplete reporting |
20 (at least 2721) | Clinical cure rates | Intravaginal imidazoles versus oral fluconazole or oral itraconazole | 4 | −1 | 0 | −1 | 0 | Low | Quality point deducted for lack of allocation concealment; directness point deducted for not reporting results of comparisons versus oral fluconazole and oral itraconazole separately |
1 (70) | Clinical cure rates | Intravaginal imidazoles versus intravaginal nystatin | 4 | −2 | 0 | 0 | 0 | Low | Quality points deducted for lack of blinding and incomplete reporting of results |
1 (95) | Clinical cure rates | Oral itraconazole versus placebo | 4 | −1 | 0 | 0 | 0 | Moderate | Quality point deducted for sparse data |
1 (50) | Clinical cure rates | Intravaginal nystatin versus placebo | 4 | −1 | 0 | −1 | +1 | Moderate | Quality point deducted for sparse data. Directness point deducted for uncertainty about definition of outcome. Effect-size point added for OR <0.2 |
We initially allocate 4 points to evidence from RCTs, and 2 points to evidence from observational studies. To attain the final GRADE score for a given comparison, points are deducted or added from this initial score based on preset criteria relating to the categories of quality, directness, consistency, and effect size. Quality: based on issues affecting methodological rigour (e.g., incomplete reporting of results, quasi-randomisation, sparse data [<200 people in the analysis]). Consistency: based on similarity of results across studies. Directness: based on generalisability of population or outcomes. Effect size: based on magnitude of effect as measured by statistics such as relative risk, odds ratio, or hazard ratio.
