Agoestina 1978 | |
Reason for exclusion | Insufficient weight change data: presented in figure without any specific numbers, other than mean gain for DMPA group in text. |
Bahamondes 2010 | |
Reason for exclusion | Mean weight change not reported. BMI included as control variable for examining bone mineral density. Study examined weight change among participants who had been using the method (LNG-IUS) for at least 7 years before the study. |
Barsivala 1974 | |
Reason for exclusion | Insufficient data: study duration not reported (our criteria was >= 3 months); also, authors did not specify whether the variance reported is standard deviation or standard error. |
Beksinska 2010 | |
Reason for exclusion | Analysis combined users of DMPA, NET-EN, or both. Authors noted the subgroups were too small to analyze separately and that differences in weight gain were not significant. |
Berenson 1997 | |
Reason for exclusion | Insufficient weight change data: means reported without any variance measure |
Berenson 2009 | |
Reason for exclusion | Insufficient weight change data: mean change reported without any variance. Of 240 who chose DMPA, 182 (76%) discontinued the method. Of the 182, 68 remained in study <= 2 more years (44 began the COC used in the study and 24 chose non-hormonal methods). Reportedly, DMPA users who had > 5% increase in weight at 6-month visit were more likely to be lost to follow up at the next visit than those who had not gained weight. Secondary report (Rahman 2012) provided weight gain (by kg categories) over any 6-month period; therefore, categories overlapped. |
Bonny 2006 | |
Reason for exclusion | Analysis combined groups that received DMPA or DMPA with estradiol supplement; researchers reported the two DMPA groups did not differ in weight gain. Method discontinuation for DMPA was 37% at 18 months. Secondary report (Bonny 2011) used weight change to examine bone mineral density but did not report means or standard deviations. Data from 2000 to 2003. |
Chen 2011 | |
Reason for exclusion | Abstract notes that weight gain was reported as side effect. Wrote to investigator regarding whether weight change was measured. Unable to obtain further information. |
Clark 2005 | |
Reason for exclusion | Insufficient weight change data: means (not mean change) presented in a figure. Text mentions mean change for DMPA at 30 months (no variance measure) and that the control group was basically unchanged. Due to discontinuations of DMPA and initiation of hormonal contraception among controls, the samples sizes were 17% (DMPA) and 19% (controls) of baseline by the last visit. |
Costa 2012 | |
Reason for exclusion | Mean change in weight was not reported. Participants were 1.5 months post-partum. |
Dahlberg 1982 | |
Reason for exclusion | Insufficient weight change data: means reported without any variance measure |
El Mahgoub 1980 | |
Reason for exclusion | Insufficient weight change data: mean change reported without any variance measure. Also, percent that lost or gained weight was reported, but no specific amount of weight was provided. |
Hall 1980 | |
Reason for exclusion | Insufficient weight change data: mean change in ‘ideal body weight’ shown in figure, except for mean change for progestin-only group reported in text. |
Havranek 1972 | |
Reason for exclusion | Insufficient weight data: mean change for one group reported without any variance measure |
Kaunitz 2009 | |
Reason for exclusion | Insufficient weight data. Mean change was reported within adverse event section without any variance measure. Data from 2001 to 2004. |
Mangan 2002 | |
Reason for exclusion | Comparison groups were DMPA users and OC users. Types of OC were not specified and might have included progestin-only as well as combination OC. |
Olsson 1988 | |
Reason for exclusion | Insufficient data for analysis: no N per group for analysis. First-year continuation rate was 59% for Norplant and 77% for Norplant-2; methods suggest these were life-table rates. |
Ortayli 2001 | |
Reason for exclusion | Insufficient data: report does not provide sample sizes used for analysis. Outcome data are from a pilot conducted in 1995 and the main study conducted from 1996 to 1998. |
Risser 1999 | |
Reason for exclusion | Comparison groups were DMPA users and OC users. Types of OC were not specified and might have included progestin-only as well as combination OC. |
Segall-Gutierrez 2012 | |
Reason for exclusion | Single-arm study comparing normal weight and obese women. The one intervention was subcutaneous DMPA. |
WHO 1978 | |
Reason for exclusion | Insufficient weight data: mean gains reported without any variance measure |
Yela 2006 | |
Reason for exclusion | Insufficient weight change data: tables show weight and BMI means (not change) by year; text mentions mean change per group over 5 years without any variance measure. Study began in 1998. |
Zheng 1999 | |
Reason for exclusion | Insufficient weight change data: means reported without any variance measure |
